Among the plants that have naturalized across this country, is the seemingly ubiquitous Queen Anne’s lace also known as the wild carrot. This herbaceous biennial originated around the Mediterranean region and western Asia. It is thought to be a wild ancestor of the carrot as both wild and domesticated carrots existed at least 5000 years ago. Anyone weeding or digging out Queen Anne’s lace from garden beds will notice the distinctive carrot smell of the taproots.

Pass almost any sunny roadside or field and you’ll find the delicate white lacy blossoms swaying in the breeze. Plants start out as small rosettes of fern-like, green leaves. The seeds can germinate throughout the growing season if enough moisture is present. Typically seeds germinate within a couple of years but they can remain viable for at least 7 years. A taproot develops where energy is stored for next year’s growth. The following spring, the plant produces more leaves, stalks and flowers. The lacy leaves are finely divided and tripinnate. The hairy, solid stem can grow up to 3 feet before the flower buds are formed.

Queen Anne’s lace blossoms typically appear from June through August in most areas. The tiny white flowers are clustered into a flat, terminal umbel from 2 to 4 inches across. Curiously, many flower heads have a single pinkish to purplish floret in the center. The color is due to the pigment, anthocyanin. For at least 150 years, botanists have been trying to figure out what purpose the dark colored floret serves. It is thought that perhaps it serves as an insect attractant but this remains to be confirmed.

Each floret on the umbel can produce 2 seeds. Since there might be 1000 florets making up the umbel, saying this plant is a prolific seeder is an understatement. In at least 35 states, it is considered a noxious weed as it displaces native vegetation. As the seeds ripen, the flower head curls inward like a closed fist or bird’s nest and turns brown. Eventually the dried seed head might detach from the stem and then it can be blown like a tumbleweed spreading its cache. This plant is especially problematic if it occurs where domesticated carrots are grown for their seed. Cross pollination could take place and the resulting seed would be useless. The seeds have hooked spines and can readily attach to cloth and fur.

Aside from its lovely, lacy flowers that hold up well in cut flower arrangements, Queen Anne’s lace serves as a host plant for the eastern black swallowtail caterpillar as well as providing a source of nectar for other butterfly species, bees and other pollinators.

Several seed companies offer varieties of Queen Anne’s lace that were bred or selected for their dark coloration. ‘Purple Kisses’ sports umbels in shades of dark purple and pink and is available from Johnny’s Seed. ‘Chocolate Lace’ from Seed Therapy comes in shades of burgundy, chocolate and dusty rose. Although I have not grown these varieties, I suspect they would also self-seed. A better option might be to try Ammi majus, called the Bishop’s flower or False Queen Anne’s lace. It is an annual with similar lacy, white flowers but I have not found it to be a prolific seeder especially if the flowers are used for cutting and not left to go to seed.

Being a member of the parsley (Apiaceae) family, Queen Anne’s lace is edible but not very flavorful. The flowers are sometimes used to make jelly. The root could be eaten when young but gets tough very fast. The seeds especially have been used for medicinal purposes for centuries. Reputedly this aromatic herb has many uses ranging from a love potion to soothing the digestive system, supporting the liver and for kidney and bladder diseases. If you are tempted to sample some Queen Anne’s lace, be very careful to identify it correctly. Other plants, such as poison hemlock have similar flowers and foliage but deadly outcomes.
As to how Queen Anne’s lace got its name, there are a number of anecdotes. Perhaps it resembled the lace collar or headdress of Queen Anne (1655-1714). Another story goes that she was tatting lace and pricked her figure leaving a drop of blood on the lace, representing the dark floret. Or it could be that the dark floret was thought to be the Queen and the white ones her maids. Geoffrey Grigson, an English botanist, conjectured that the name was in honor of St. Anne, the mother of the Virgin Mary and the patron saint of lacemakers.
However Queen Anne’s lace got its name, one has to be in awe of how widespread it has become. Because plants are short-lived but prolific seeders, one way to control it is to remove the flower heads before they go to seed. They do make delightful cut flowers so make use of them in arrangements. You get to enjoy them and there is less seed out there.

Favorite Summer Plants For Hummingbirds

Posted on by

By Pamm Cooper, UConn Home and Garden Education Center  

Every spring I make a list of the plants that hummingbirds visited the   most the year before, and then my search at garden centers and nurseries begins in earnest. The plants I look for are the ones that not only hummingbirds seem to benefit from the most, but also the ones that bloom the longest. I also select the plants whose flowers I enjoy as well.  

Although annuals generally have the longest bloom time, there are some perennial ornamentals that are very attractive to hummingbirds and are worth considering for a garden or a landscape. Including a small group of these plants would be a great benefit to hummingbirds as they visit your property.  

Obedient plants, Physostegia virginiana, can bloom from early June through September. These drought tolerant perennials may get 3 feet tall and some will slowly spread. If that trait is a problem, The ‘Manners’ series such as the white ‘Miss Manners’ obedient plants are not spreaders. The flowers are also attractive to butterflies, especially tiger swallowtails, and pollinators.  

Native swamp milkweed, Asclepias incarnata, is also visited by hummingbirds. This plant likes moister soils than most milkweed, and mine is planted near a birdbath that gets emptied frequently to add fresh water. This milkweed, along with butterfly weed A. tuberosa, can be deadheaded to promote rebloom.  

Hyssops, Agastache spp., are also a favorite of hummingbirds, and most have a long bloom period, some starting in late spring. The ‘Kudos’ series with small flowers that are yellow, pink or orange are the ones visited the most by hummingbirds on my property. Another favorite is ‘Boa’, which has larger flower spikes lasting a good three months. Deadheading all will prolong bloom time.  

Annual flowering plants that are a favorite of hummingbirds include Salvias, cardinal climber, Fuschias, Lantanas and Cupheas. All are easy to grow, and all but the cardinal vine can be used in containers, hangers and window boxes.  

The cardinal climber, Ipomena x multifida, is an attractive, fast-growing annual vine that has small, brilliant red trumpet- like flowers. You can save seeds from this plant and use them next year. One plant can grow to fill a large trellis, and you may need to corral it in if it starts reaching out for nearby plants.  

Of the Cupheas, the ones most visited, in my experience, are the large firecracker plant, C. vermillionaire, and the smaller one, C. schumannii, also called the orange cigar plant. The former is superior, with a compact, mounding habit and continuous bloom of orange tubular flowers until frost. If the smaller cigar plant is planted directly in the garden, give it some room as it sprawls somewhat.

Annual Salvias like the “Rockin’ series, the ‘Black and Blue’,  ‘Roman Red’ and the ‘Hot Lips’ salvias are the ones I always have in my containers or plant directly in the ground in spaces I leave for them. I would not venture to guess which ones hummingbird prefer, as they visit all of these throughout the day.  

There are a couple of shrubs that I learned by chance observance are favorites of hummingbirds. These are Weigelas, and butterfly bushes, Buddleia davidii. There are Weigelas that bloom only in the spring, some that bloom in spring and then again later in the summer through fall, like the ‘Sonic Blooms’, and some that bloom throughout the year, like ‘Crimson Kisses’ and ‘ Peach Kisses’. The last two are smaller shrubs which have a rounded habit.  

The plants I have included in this brief article are only a small example of plants that the average gardener can include on their property in gardens or containers of some type. I will mention that while I do have a hummingbird feeder, the hummers I see are favoring actual flowers over that source of food. Downy woodpeckers and orioles do visit the feeder instead, so it is useful to them, I guess. I may start calling it my downy feeder, at least during the summer.

Seeing Ghosts in Your Garden?

Posted on by

By Emily Leahy, UConn Plant Diagnostic Lab

While meandering around my backyard this past weekend, I spotted a striking plant which I had never seen before. At first instinct, I assumed it was a particularly unique fungal species and snapped a couple pictures. My curiosity having been piqued, I did some research and learned that it was in fact not a fungus, but a parasitic plant reliant on fungus – Monotropa uniflora. Its name is self-descriptive; Monotropa, illustrating the single turn of its shepherd hook shape, and uniflora, depicting the lone flower produced on each stem. It is also known as “Ghost Plant” or “Indian Pipe.”

Perhaps the most unusual feature of Monotropa uniflora is its color, or lack thereof. While mostly white-colored overall, hues of pink can be visible along with black flecks spread along the plant. The translucent nature of the plant is derived from the absence of chlorophyll, a green pigment and key component allowing autotropic plants to perform photosynthesis.

Autotrophs are organisms that convert abiotic (non-living) sources of energy, like sunlight, into organic compounds they can use for food production. Most plants have this ability, using the chemical reactions in photosynthesis to produce carbohydrates for their own nourishment. However, Monotropa uniflora, a heterotrophic plant, cannot carry out such processes. They seek the organic compounds needed to sustain themselves from external sources. Autotrophs are often referred to as “producers” and heterotrophs “consumers” to illustrate this distinction. Since Monotropa uniflora is not directly dependent on sunlight for survival, it is often found in shaded areas and forests.

This all begs the question – where does Monotropa uniflora get its nourishment from? The answer comes in the form of its parasitization of mycorrhizal fungi and surrounding trees. The term “mycorrhizal” is used to describe fungi that form a symbiotic relationship with the roots of its host plant. The interaction is mutually beneficial – mycorrhizal fungi receive sugars and carbon from its host, which in turn is aided by the fungus in its absorption of water and nutrients. The root system of the host plant is used as a transportation highway in these interactions.

Monotropa uniflora inserts itself as a third player in the relationship, disrupting its balance. In a clever sleight of hand, the parasite tricks the mycorrhizal fungi into thinking it is forming another symbiotic relationship as its root system interacts with the fungal mycelium. However, the benefits of this interaction are strictly one-sided as Monotropa siphons the carbohydrates, initially derived from the mycorrhizae’s host trees, for its own consumption. This is not severely detrimental to the fungi or host plants, but it certainly detracts from the vigor of their symbiotic relationship and the amount of available resources transferred between the two entities.

Monotropa uniflora has a wide range of distribution throughout the U.S., so it is possible to see these fascinating plants in action in a variety of locations. Its flowering season ranges from early summer to early fall and it thrives even after seeds are released.

A microcosm of ecological phenomena, Monotropa uniflora is quite the unique find. It is enthralling not only to observe, but also to know the complex interactions that occur just below ground. I say we can overlook its parasitic tendencies and appreciate its role in the delicate balance of our natural world – after all, everyone loves a good villain, right?

Hyped for Hydrangeas

Posted on by

Nick Goltz, DPM, UConn Home & Garden Education Center, UConn Plant Diagnostic Lab 

When I moved to Connecticut in July of 2021, I remember driving through neighborhoods looking for somewhere I might eventually want to live and being struck by the beautifully-landscaped yards that each home seemed to showcase. I particularly remember being impressed by the tidy hedges of hydrangea, filled with lush globes of blue, pink and purple flowers. Can you think of a flower more emblematic of breezy, long summer days by New England coast than the hydrangea? I’ll wait. 

Hydrangeas are a fascinating group of perennial plants with some unique quirks that make them a fun addition for the home garden. The genus is native to Asia and North America, but the species grown most commonly around the world, Hydrangea macrophylla, is native to Japan and has been bred extensively for hundreds of years, resulting in many cultivars. They are also bred with other species to help select for cold tolerance or inflorescence (flower cluster) shape.  

Hydrangea macrophylla are commonly known as “bigleaf hydrangea”, but may also be called “lacecap” or “mophead” hydrangea, depending on the shape of the cultivar’s inflorescence. While many species of hydrangeas have white flowers, bigleaf hydrangeas are prized for their beautiful inflorescences that act as a natural pH indicator of the soil the plants grow in. The petals of flowers will change depending on how basic or acidic the soil is. Flowers will be blue, indigo, or deep purple in acidic soils with a pH of 5.5 or less. Plants gown in a slightly acidic soil with a pH between 5.5 and 6.5 will have a mix of purple hues. Hydrangeas grown in neutral to basic soils with a pH greater than 6.5 (especially 7 and up) will generally have fuchsia to pink-colored flowers. Many gardeners will amend the soil of their hydrangea beds from year to year to achieve the color that they hope for.  

Many folks know of the color-changing capabilities of hydrangeas, but keep reading for a few tips on how to properly care for them beyond adjusting soil pH. Hydrangeas prefer moist, well-draining soil and a sheltered spot with partial shade. Some cultivars tolerate full sun well, but must be watered consistently to look their best. Hydrangeas do not grow exceptionally large and are considered “low fire risk”, so are a better choice for planting near the home.

This ‘Summer Crush’ hydrangea near my house will have purple blooms in acidic soils and fuchsia blooms with basic soils. Because both colors are appearing, I’m guessing this soil must have a pH between 5.5 and 6.5!

There’s a reason why coastal New England towns seem to be filled with hydrangeas while interior towns, particularly for our friends in Vermont, western Massachusetts, Maine, and New Hampshire, have fewer. Bigleaf hydrangeas can tolerate cold temperatures, but only to an extent. Depending on the cultivar, bigleaf hydrangeas grow best from zones 6 to 8. Most cultivars will survive zone 5 winters, but might not flower well without protection – harsh winter temperatures, especially when paired with low snow cover, can kill flower buds.  

Flower buds form on old growth for most cultivars of bigleaf hydrangea. Because of this, many folks will accidentally prune away flower buds in winter, resulting in poor flower production come summer. For this reason, it’s important to never prune bigleaf hydrangea in fall, winter, or spring. Only prune away the bare stems from the previous year when you see that no new growth is being produced from them, or in summer when collecting flowers for the vase on your kitchen table!  

 If you find the twiggy winter appearance unsightly and can’t help but prune, if you struggle with deer feeding, or if you live in an area with common late spring frosts, consider planting a “reblooming” bigleaf hydrangea. There are a few cultivars, such as ‘Endless Summer’ and sports, that will produce flower buds on old growth and (usually) a second flush on new growth. Alternatively, you could plant other species of hydrangeas, such as smooth hydrangea (Hydrangea arborescens), or panicle hydrangea (Hydrangea paniculata), which tend to be a little more cold-hardy, or oakleaf hydrangea (Hydrangea quercifolia), if you’re looking for a hydrangea for an area with very hot summers.

Unbeanlievable: Here’s a Vegetable That Produces All Season Long 

Posted on by

Abigayle Ward, Soil Science Graduate Student

Full of fiber, packed with protein, and great to grow, beans have been a staple in the diet of humans for thousands of years. Native edible beans can be found on every continent but Antarctica, although many of the beans we eat today are domesticated varieties that originated in South America, Europe, and Asia. Fabaceae, the bean family, is one of the largest families of plants in the world, with over 20,000 species described. As legumes, beans can convert nitrogen in the atmosphere into nitrogen useable by other plants, making them very useful to integrate into crop rotation for savvy home gardeners who want to save a little money on nitrogen fertilizer. In fact, excessive nitrogen fertilization of legumes can inhibit the natural nitrogen-fixation process, so use only a low-strength nitrogen fertilizer if absolutely necessary. Legumes can even be used as cover crops in the winter to prevent soil erosion and provide a boost to your soil health all winter long. You can direct-seed beans and still get production all season, meaning Connecticut gardeners can get beans in the ground now. 

Fava beans (Vicia faba) are grown all around the world, very adaptable to many climates, and are generally very easy to grow. They are cold-tolerant and can be grown all the way down to USDA Hardiness Zone 3. In Connecticut, for the best results, you should plant fava bean seeds in the early spring in a place that gets full sun and doesn’t stay too moist. They will take about three months to begin producing beans but will continue producing throughout the season and into the fall. Some frost-resistant varieties will even survive temperatures below freezing, and since they self-pollinate, bees are not necessary for the production of pods. Fava beans do not require trellises, but some larger varieties may benefit from cages or trellises for additional support. In the summer, pollinators love the flowers, and understandably so – bean flowers not only signal the coming produce but are also eye-catching. Many varieties have white and dark red flowers. Some varieties have pink flowers. Bean pods can be harvested and eaten whole if they are young and tender. It is important to note that some people may have an adverse reaction to consuming fava beans, a metabolic disorder called favism. Favism causes anemia in response to the inhalation of the plant’s pollen or consumption of the beans. Be sure to check with your doctor before trying these beans for the first time.  

For “summery” beans that are native to central and south America, you can try planting kidney, cranberry, appaloosa, or navy beans, all in the genus Phaseolus. Perhaps the delight of beans in the Phaseolus genera is their diversity in appearance. Appaloosa beans are especially whimsical, with white, brown, and reddish mottling. They strongly resemble the horse for which they are named. Some of these species behave like pole beans, meaning they will need to be trellised, while others behave like bushes, meaning they should not need to be trellised. The seed packet should indicate whether they will need to be trellised. As with fava beans, be sure to water Phaseolus when the soil seems dry, taking care to avoid watering the leaves. Excessive leaf wetness may increase the likelihood for fungi to grow and cause disease. 

No matter what bean you try growing, pests and disease are ever-present. Aphids, bean beetles, and European corn borer are all possible bean pests. Beans are susceptible to diseases like powdery mildew, Fusarium wilt, and bean rust. Selecting disease and pest-resistant varieties will reduce the risk of yield loss. Like most legumes, the ideal soil pH for growing beans is 6-7. Since native Connecticut soil typically has a pH closer to 5.5, be sure to send a soil sample to the UConn Soil and Nutrient Analysis Lab to test the pH (and nutrients!) of your soil before planting to ensure you get accurate recommendations for any amendments your garden may need to allow beans to thrive!

Narcissi and the Reflections of Spring

Posted on by

By Abigayle Ward – Soil Science Graduate Student, UConn Department of Plant Science & Landscape Architecture

According to an ancient Greek myth, all those who had fallen in love with the young man Narcissus were met with contemptuous rejection. On a hunting trip, Narcissus stopped to drink from a pond and became enamored with his own reflection. Cursed to never experience a requited love of his own, he stared at himself until his death, and his place was taken by a flower.

While it remains disputed whether the character was named after the flower or vice versa, the enduring significance of the narcissus as a harbinger of spring is uncontested. With a native range spanning throughout most of Europe, northern Africa, and parts of Asia, legends describing this culturally significant early-season perennial have been told since antiquity. In China, daffodils are carefully grown to bloom for the Lunar New Year, which began this year on January 29th. Their Mandarin name, shuixianhua, literally translates as “immortal water flower”, attesting to their resilience throughout the early season cold.

The Royal Horticultural Society in the United Kingdom describes 13 different types of narcissi based primarily on morphological appearance and when they bloom. Some have long trumpets, while others have multiple flowers to one stem. Others have small trumpets and many petals, called ‘double daffodils’, while others still have few petals dwarfed by large, bowl-shaped trumpets. Daffodils also come in many interesting color combinations – while most of us are familiar with the classic yellow petals and orange trumpets, they also come with white petals, white trumpets, and some even have shades of salmon pink. As one of the earliest-blooming flowers in your garden, they add a lovely splash of color to an otherwise brown landscape. In beds, they go well with red or pink tulips. By themselves, daffodils make good borders, particularly if different color combinations are intermixed to create visual intrigue.

While it is too late now to plant daffodil bulbs with the guarantee of blooms, they can still be safely planted. If you have some bulbs and want to give them a try, be sure to plant them in a sunny spot with well-drained soil at least 6 to 8 inches below the surface. They may sprout, but not form a flower. Do not fear: Daffodils are quite resilient and will likely flower the next spring. If you want to wait, the ideal time to plant daffodils for blooms in the spring is November.

If you find an already-blooming daffodil at your local garden center, it can be planted in the ground any time after the blooms themselves have faded. Both the bulbs and the foliage are frost-hardy well into sub-zero temperatures, making them well-suited for growing in the unpredictable winter weather of Connecticut.

After the flowers have bloomed, you may wish to cut the flower stems and bring them indoors for some bright colors. If you leave the flowers on the plants, be sure to deadhead them as soon as the flowers begin to wilt. If daffodils are allowed to go to seed, the plant will divert precious nutrients and energy away from the bulb. Once the plant has finished flowering, only the foliage remains. While it is tempting to remove the foliage, the leaves are collecting energy and creating food for the bulb via photosynthesis. If the leaves are removed too early, the daffodil may not flower the following spring. Some gardeners like to tie up the leaves in rubber bands or braid them to keep them out of the way, although it is generally best practice to leave them alone until they turn brown by themselves. Damage to the leaves could introduce pathogens or attract pests, which could impact the ability of the plant to flower next year.

With proper care, daffodil bulbs can multiply, ensuring many blooms come back year after year. As we move forward into the season of renewal for ourselves and our gardens, consider planting some daffodils to add a bit of sunshine to your home landscape.

Yes, You Can Grow Orchids!

Posted on by

By Dawn Pettinelli, UConn Home and Garden Education Center

Some favorite booths at the CT Flower and Garden Show this past weekend were the ones filled with orchids. Orchids are becoming more popular as houseplants and many folks are finding that they can be grown successfully in the home without elaborate care or special equipment. If you’re in a traveling mind, check out the Orchid Exhibit at the New England Botanic Garden in Boylston, MA that runs through March 23, 2025.

Orchids are grouped into two general divisions. Epiphytic orchids naturally grow on trees in the tropics. Trees are used for support. Water and nutrients come from rain, bird droppings and organic debris collecting around the roots. Terrestrial types will grow in a highly organic soil. While epiphytic orchids may tolerate or even enjoy a dry, dormant period, terrestrial species, in general, need to be kept moist throughout the year.

Two styles of growth are exhibited by orchids. Monopodial orchids grow in an upright direction from the central stem on which aerial roots and flowers develop. Sympodial orchids generate new growth from the base of the plant. As the new stems mature and bloom, younger shoots once again are produced and the cycle is continued.

The orchid family is organized into several genera (each called a genus) which may contain from one to many species. Much hybridization has occurred and the names can be baffling to a novice. For instance, hybrids resulting as a cross between Cattleya mossiae and C. warscewiczii are labeled Cattleya x Enid, the ‘x’ indicating the plant is a hybrid.

Some of the easiest orchids for beginners are phalenopsis, paphiopedilum, epidendron, oncidium and cattleya. Not every member of each genera can be successfully grown in the home so be sure to check with your source. Almost all colors are available and blossom size may range from very tiny to several inches in diameter.

The basic requirements for orchids are good ventilation, 40 to 50 percent humidity, light, proper watering and a well-draining potting mix usually composed of fir bark. Often osmunda fiber, tree fern and/or perlite are added to the fir bark.

Specific cultural requirements vary as to the species. Some tolerate higher light levels than others. Many varieties of the orchids listed above prefer 55 to 60 degree F nights and 65 to 68 degree F days although cattlyas, epidendrons and oncidiums like it about 10 degrees warmer. If growing on a windowsill, put the varieties that like it cooler closer to the window. Make sure leaves do not touch the glass.

Ways to increase humidity include grouping plants together, placing on gravel lined trays filled with water, frequent misting or use of a humidifier. Plants should not sit in water and the foliage, if misted, should be dry by evening. Don’t keep plants too close together as good air circulation helps prevent diseases.

Watering is perhaps the trickiest part of growing orchids. There is not accurate rule for when to water because it depends on the size of the container, the type of growing medium, temperature and light conditions. Obviously, plants will have to be watered more often in hot, dry weather and less during cool, damp periods. When watering, soak the potting material thoroughly. Do not water again until the medium feels dry to the touch. If in doubt, do not water.

Since fir bark contains virtually no nutrients, plants have to be fertilized on a regular basis. Some recommend fertilizing at every third watering with a half strength orchid fertilizer. It is best to place plants in the sink and water until it drains from the pot, not putting the plant back in its saucer until it is thoroughly drained. Special orchid pots are available with enlarged drainage holes. Fertilizers should just be applied when plants are actively growing.

Orchids are a plant you have to experiment with but once you’ve experienced success, you will find that as a hobby, they can be quite contagious. Those seeking more orchid information might want to check out the Connecticut Orchid Society (www.ctorchids.org) or the American Orchid Society (www.aos.org).

Preparing for Spring on CRIS Radio

Posted on by

CRIS Radio: Focal Point 2/21/2025

Heather Zidack from the UConn Home & Garden Education Center talks to host, Stephen Thal, about climate change in the garden, houseplants, seed starting and more!

Transcript

Transcript 

00:00:01 Stephen Thal 

Hi, welcome to another segment on focal Point. This is Stephen Thal and I'm your host for today's program. 

We're going to be learning a lot about getting ready for the spring when we realize the weather is still not quite ready for spring flowers, but we want to get everybody thinking about it. So when the time comes, they'll have some ammunition and be prepared to get in there and get their hands dirty. 

00:00:31 Stephen Thal 

To help us understand that we have Heather from the plant and science program at the University of Connecticut. Welcome back Heather. 

00:00:41 Heather Zidack 

Hi Stephen. Thanks for having me back! 

00:00:43 Stephen Thal 

Yeah, it's great because you gave everybody some spirits to think about and encouragement. One of the things that we've been reading about lately is about climate control. And we were curious, you know, as we look around the country, different things are happening. People can't seem to explain why the weather has changed so drastically, and we're sure that this will impact the way we think about our flowers and the way we want to put a garden in and do herbs. Can you help us understand what climate control may be doing to this? 

00:01:22 Heather Zidack 

Yeah. So there are some things that we are noticing, especially from people just calling into our office with , um, in relation to climate change and a couple of the big things that have happened in 2023, I believe it was the fall of 2023 they did change the USDA hardiness zones. Which, when you're shopping for plants, your zone is actually going to tell you the coldest temperature that plants can tolerate to survive in your area. And so Connecticut, we're about a Zone 6 at this point, is the safe one. But it did shift and so there are parts of the state that are even seeing some warmer. Especially Shoreline is a little closer to zone 7. 

And you can look that up through the USDA to see the change from the zones. But that's a big change. Part of that happened because they had more data points and they could actually get more weather stations to report on what was going on, so it became a little more accurate in that sense. But we are also seeing some climate change effects happening as well. 

We’ve seen you know a lot of flooding over the past couple years. Remember up in you know, Vermont, New Hampshire, they had some of those floods that led to crop loss and contamination of fields. Storms with heavy winds can damage a lot of crops sometimes. 

And higher heat and humidity can affect your gardens as well.  

So if you're looking for management techniques, the first thing that you can do is make sure that you're providing enough water and nutritional support to your plants to endure any stresses that they might see during the growing season. So get a soil test. 

Have your your soil ready to go. Know what fertilizer you need. 

And make sure you're watering. Not too much, not too little. But you're keeping up with what the plants need. That's going to help them build their defenses, just like when we take vitamin C in the winter to prevent colds. 

If you're going to be seeing some hot weather come around and there's heat management strategies, one of the first things you want to do is remove weeds. It actually helps to increase air flow around the plants and also remove competition for some of those nutrients and water that I talked about a minute ago. 

You can also use shade cloth or something to kind of keep the plants out of the hot hot heat of the sun, especially on those really hot days. If you're able to, If you've got potted plants and you can move them to a a sheltered spot on those hot days it works for them. 

But those are a couple heat management strategies. 

00:03:58 Stephen Thal 

What about bugs? 

00:03:59 Heather Zidack 

For me? Oh. 

00:04:00 Stephen Thal 

What about anima-, little bugs like fleas, ticks, beetles? 

00:04:04 Heather Zidack 

Yeah, well, it's something that we notice in the garden and when we see these different fluctuations in heat and temperature. We see a lot of fluctuations in our insect populations. 

So we do see there have been some instances where you haven't had the ability to really have a good kill off of everything in the environment. And so the next year we see more bugs coming out. Our office deals primarily with the garden insects and the pathogens. So seeing things like-Last year, there was a lot of Japanese beetles. Last year there was a lot of fungal infections. 

Really, the best thing that you can do for that is again making sure any weeds are gone so they don't have anywhere to hide in your garden. You can also space your plants as they're recommended in order to make sure that you're having good airflow and good movement in between them, and again you're removing hiding places and you also want to prune all your woody ornamentals to encourage air flow too. 

So if those are some good strategies for that. 

00:05:09 Stephen Thal 

You mentioned fertilizer and doing soil testing. Is there a phone number that people can call and how do they do that? 

00:05:17 Heather Zidack 

Absolutely, so soil testing can be done anytime that the ground is not frozen, so I think we're in the one time of the year where we can't do it right now, but once the ground thaws, the UConn Soil Nutrient Analysis Lab is available for testing.They do a standard nutrient test and that covers all the basic nutrients that you would need for your home garden as well as pH so their phone number is 860-486-4274. 

Again, that's 860-486-4274. 

00:05:57 Stephen Thal 

Ok, Great. 

00:05:58 Stephen Thal 

So we now got to prepare for maintaining our house plants. As well as taking care of those that we choose to go outside and give them some fresh air and not allow too much heat, how are we going to do this? 

How do we prepare for it? 

00:06:16 Heather Zidack 

Yeah. So one of the things that you want to make sure that you're doing, it's still a little too cold to put anything outside just yet. You want to remember that our target is 50° at night before you're putting any plants outside. 

What you want to do with your house plans inside is you want to check for water. Make sure that they're accurate adequately-They have enough moisture in the pot. 

You want to check with your fingers, make sure that it's not clumping up too much in your hand. You want to make sure that it's also not like sand texture. You want to make sure there's an even moisture you might not need to water as much right now, especially if your plants are dormant, just like we don't think about hydration much in the winter, because we're not outside and in the heat, plants are the same way. So check before you water every time. 

The other thing that you can do right now is dust the leaves to scout for pests and disease. 

You can also start fertilizing your house plants when you see new and active growth. So like if there's new leaves, if there's new buds, if they're new shoots, those are signs your plant is waking up and you could use a little food at that point. 

And you want to make sure that you're checking any bulbs or plants that you have in winter storage. So if you dug anything up from your yard, like Canna lilies or Gladiolus bulbs or anything like that, check those bulbs in storage. 

Make sure they’re firm. Make sure there's no discoloration or smell to them and they should have some kind of humidity with them, but not too much. So if you had stored them in peat Moss, maybe missed in with the bottle for a second, but they don't need sopping water just yet. So you want to check all of those things. 

00:07:56 Stephen Thal

And what kind of tools do we need to help us with our projects?

00:08:03 Heather Zidack 

So big thing right now is going to be pruning season, so you can use-depends on the the size of the plant. But if you're outside, you want to have some some good hand pruners or some loppers- Depends on the size of your branches, but pruning right now is an advantage because there's low disease and low pest pressure outside, so plants can easily recover without being exposed to any other diseases. 

In general, people use hand pruners or like I said Loppers which are a little bit larger to cut their their trees back. 

And the rule that you follow is the rule of thirds. You don't want to cut off more than 1/3 of the entire plant if you want to leave 2/3 standing. And that ensures that there's enough of a ratio between roots and shoots that there's healthy regrowth.  

With that being said there are some different pruning techniques that can be suggested for different species of plants.  

So always consult with an arborist or landscaper or give our office a call. If you ever have any questions. 

00:09:10 Stephen Thal

And what about choosing the right fertilizer?

I know there are many different kinds. I know I've heard of fertilizer from Maine where they save all of the lobster shells, crab shells and mix them all together. And that's supposed to be good too, for your plants. 

00:09:29 Heather Zidack 

There's all kinds of fertilizers out there and so. There's different products that are organic. You have things like manures and composts and things like that. Also have synthetic materials like regular. You have coast of Maine like you talked about. The important thing when you're looking for fertilizers, we always recommend getting that soil test first. Because you want to know what your baseline is, right? 

You want to know where you're starting before you add anything else. Once you have that, the soil test is going to tell you in general terms you have 3 numbers on a bag. If you look at a bag of fertilizer, there's going to be usually something like the effect of 10-10-10, 5-5-5, 10-15-10 20-20-20, something like that. 

Those 3 numbers there, those 3 numbers represent in this order nitrogen, phosphorus and potassium. So when you're looking at those numbers, you're actually looking at a percentage of how much of that nutrient is in the bag. 

00:10:31 Heather Zidack 

So once you have your soil test for example and it says you are deficient in potassium. So, NPK, your third number there would be the one that you would want to add a little bit more of you would maybe look for something like a 5-5-10. 

00:10:47 Heather Zidack 

It all depends on what your soil test comes out as and what you're actually looking for with a specific crop, so it's hard to give a generalization, but knowing how to read that bag is your first step in knowing what to shop for when you're ready. 

00:11:02 Stephen Thal

If we're going ahead and deciding to plant herbs, is this a good time of the year inside to get those started?

00:11:11 Heather Zidack 

Absolutely. There's a lot of plants that you can start right now. Herbs are going to be great for kitchen gardens. You can pretty much start them any time of year. 

Great for culinary purposes, but they're also loved by pollinators. The Swallow tail Caterpillar in particular loves things like dill and parsley plants, and they're all over them in my yard. So I actually grow a little extra just for them. 

00:11:35 Heather Zidack 

You get a lot of fragrance and texture out of all of the fresh herbs, which is fantastic, and it can be easily done, indoor or outdoor. 

So right now you would want to start everything indoors that you want. The really cool thing with herbs is that there are some of them, like basil is an example. You know how they sell the basil plants in grocery stores, right? 

00:11:56 Stephen Thal 

Right. 

00:11:57 Heather Zidack 

So what you can do is you can actually cut off a stem of that basil, remove the leaves up to like the first leaf, maybe the first 3 or 4 leaves up there, put it in water, and it'll send out its own roots that you could then put in a pot yourself. 

00:12:12 Heather Zidack 

So you don't necessarily even need to do anything with seeds. You can do cuttings to keep your herbs going. 

00:12:17 Heather Zidack 

The only thing I would recommend is to plant if you're going to plant mint. Keep it in containers and keep it away from the ground. Don't put it outside unless you want to grow it for the rest of your life. It does have a pretty aggressive tendency, and once it hits the ground and gets rooted in, it can just grow and grow and grow. And then you have mint in that area forever. 

But other than that, herbs are great to start right now. 

00:12:43 Heather Zidack 

A lot of people are starting, especially if they do cut flowers and small seeded plants right now. Like if you think snapdragons. If you think Cosmos, some of those they need to start now because they need a lot of time to grow. Veggie wise. People are starting things like broccoli and Brussels sprouts at this point. 

Most people have started like onions and shallots by now, but you probably still have time if you were to do it like right now. And so really, there's a lot of different veggies that you could be starting right now. 

00:13:19 Stephen Thal 

Yeah, those are are very critical things that we have to keep keep aware of. 

00:13:26 Heather Zidack 

Yeah, timing is everything with when it comes to starting. 

00:13:30 Stephen Thal 

Right. And this is Stephen Thal with another segment on Focal Point and we're interviewing Heather from the Yukon plant and Science program and they offer a lot of help to citizens in the state. In terms of not only analyzing the soil, but talking to you about the different kinds of plants or herbs that you might want to consider starting and what has to be done to maintain them, and we know that Climate change has strongly impacted the way we have to do our season so that we can take all of our hard labor in to make sure we get some good results and not have it fail for us during the during the coming growing season. 

00:14:20 Stephen Thal 

I think it. 

00:14:20 Heather Zidack 

Yeah. 

00:14:21 Stephen Thal 

I think it forces us to have a have a little more time to work with this. 

00:14:30 Heather Zidack 

Yeah, it's really interesting. You know the frost date is a big thing that's important when you start planting seeds and when you start planting outside, especially with vegetable gardens and a lot of gardeners- 

I remember, even when I was young, used to plant right around Mother's Day, which is in mid-May. In the past couple years, we probably could have done that, but you have to really watch the weather. 

I've seen a few seasons where you're waiting past Memorial Day, which is the end of May at this point, and it's-For me, Memorial Day has become more of that target. Be like-this Is definitely the weekend things are going to go in. 

You can keep an eye on the weather. And as long as the weather is staying above, you know, we're not getting frost. You can put your seedlings out, but you're taking a risk because we can have a frost anytime in that spring, part of May, and if you do you can lose your seedlings, so if you do put anything in the ground a little bit early do so with caution. 

Keep an eye on the weather and be prepared to be able to run out and cover them if you need to. We always recommend like fabric coverings like either a towel or a sheet or a pillow case or something like that to cover your plants if they're in the ground and we have a frost coming. Using anything like plastic is definitely going to exacerbate the problem and cause more damage when it comes to frost and freezes than anything else. 

So I would say. Look at your frost date. 

I know the Farmers Almanac has a target frost date that you can look up, but if you want to play on the super safe side, I plant right around Memorial Day and that's a good time to plant, be outside and make sure that you're keeping an eye on the weather when you're putting things out. 

00:16:21 Stephen Thal 

Are there specific questions you should be asking the local gardeners or when you go in and buy things? To make sure you're getting the things that you want, especially the different plants. 

00:16:35 Heather Zidack 

Yeah, you want to look for quality seed whenever you're purchasing. In general, most garden centres have. Seed that is timely. So you're going to see, just like we have certain products in the grocery store that have like an expiration date. There are seeds that have that date planted on the back. 

They should be packed for this year and I believe they have to sell seeds that are packed for this year, so that's not something that you have to worry about too much, but it is good to know where to look for that information. Look at where It will say “packed for” and then it will have the year on there. 

It'll also show the germination rate, which is how well, the seed will actually sprout. That's advertised on the envelope as well as like a quality control and so you want to make sure that it's got a good germination rate. 

I've seen seed products before that I've purchased where they had a note on the envelope that said last year we had a low germination rate. So this year we're giving you extra seed and in the envelope it was a little heavier pack than what it had been in previous year. 

So you want to make sure you've got a good germination rate. You want to make sure that there's a a date that's packed for this year. Those are both more important than anything like brand. You want to make sure that you're looking for good seed when you're starting. 

Something to keep in mind is that there are- if you are someone who saves seeds from year to year, you want to make sure you're storing them well. Keeping them in a cool, dry area. 

And if you do have seeds that are either seed that you've saved and you have a history of, like plant disease in previous years, or if you've bought untreated seeds and you have a reason to have concern that maybe you had some kind of, you know, plant disease a previous year. You can have your seeds treated with something called hot water seed treatment and our plant diagnostic lab does that. 

00:18:37 Heather Zidack 

To help make sure that there are no pathogens on the feed when you plant them in the ground to give them a healthy start. So that's an option, especially if you have a history of disease in your garden that some gardeners do like to take advantage of. 

00:18:52 Stephen Thal 

Oh, that's good. 

00:18:53 Stephen Thal 

Are there any special plants that some of the gardeners may be putting out this for sale that we need to be aware of, especially for the disease? 

00:19:04 Heather Zidack 

So you want to be careful with-I will say if you're looking at things like plant swaps and you're going to like Garden Club plant swaps and things like that, we did help out a lot of garden clubs last year as they were looking at how to do this while still being aware of the jumping warm issue. And so jumping worms are an invasive worm that are going from property to property and the best way to make sure that they don't transfer between properties is to make sure that your roots of your plants are cleaned off.  

So. A lot of, especially at plant swaps, a lot of these garden clubs were having people dig their plants that they were willing to donate. Rinse the plants off at the roots. Repot them into soilless potting media. 

And then they were willing to trade them and and exchange them at these swaps. 

So you want to make sure if you are going to plant swaps, they are taking some kind of precaution like that and if they are not, you can still take the plant home but you want to make sure that you're doing the rinsing of the roots to make sure that nothing is coming onto your property. 

00:20:18 Heather Zidack 

We had a lot of garden clubs that were able to take some of these procedures and be very successful with their plant swaps and not have to worry about it at all. But education is that first step in knowing how to manage this issue right and so that way they knew that they had to rinse the roots. They had to keep their gardeners educated on how to prevent this from spreading, and they were able to still have plant swaps and stuff, so not encouraging any fear of plant swaps. 

Just kind of giving you that heads up of tou may need to wash the roots if you bring some. 

00:20:50 Stephen Thal 

Yeah, those are very important things. And I think also as a person who may be out with your plants or just sitting in the yard admiring them, I think we need to remind people to wear their sunglasses and to wear a hat and use proper sun protection. 

00:21:07 Heather Zidack 

Very important. I always used to tell my colleagues when I worked at a garden center, I'd say water the plants and water yourself. 

00:21:16 Stephen Thal 

That's good. 

00:21:17 Stephen Thal 

Yeah. Good. 

00:21:20 Stephen Thal 

Any other items you'd like to have us our listeners be aware of and enjoy their spring fling in the garden and in their house plants. 

00:21:32 Heather Zidack 

Yeah. One of the things that I would love to make everyone aware of is that the Connecticut Flower and Garden show is coming up at the end of February. It's going to be February 20th to 23rd at the Hartford Convention Center and the Home and Garden Education Center, Myself and my colleagues will be there answering garden questions. 

So if you have garden questions, please feel free to stop by and say hi to us. We've also got speakers that are going to be there every single day. And it's a nice taste of spring because a lot of local landscapers and garden centres will do full on displays. 

00:22:10 Heather Zidack 

It's very cold. We're starting to see Snow and it's nice to take a break and just have that smell of fresh flowers all around and everything. So it's a great opportunity to get a taste of spring. And get your garden questions answered. If you need to see us. So it's really good coming up. 

00:22:29 Heather Zidack 

The other thing that I have for advice, if you're looking for spring a little bit early is if you have anything like Dogwood, forsythia, crab apple in your house or in your property, you can take cuttings of them and put the branches in warm water. 

And they could force the flowers to open right now. So you could get a little bit of spring early in your house by doing that. 

00:22:53 Heather Zidack 

The other thing that's really important to keep in mind is that if you are an avid gardener. It's a good time to take any of your tools that are in the shed and make sure they're in proper working order. Make sure that all of the handles are tightened. 

Make sure everything is sharpened if it needs to be sharpened and paint the handles with a bright red or bright orange paint to help you see them when you put them down in the garden. 

00:23:17 Stephen Thal 

Yeah. And I think also lawn mowers or any working tools like that should be taken to a mechanic to make sure everything's working. 

00:23:24 Heather Zidack 

Absolutely anything with an engine. Don't do yourself. 

00:23:30 Stephen Thal 

Yeah. Sounds like you've had some experiences. 

00:23:34 Heather Zidack 

Yeah. 

00:23:35 Stephen Thal 

Now in terms of plants, we have to watch out for some of these poisons that may be used to help plants. Are there any that we should avoid? 

00:23:47 Heather Zidack 

So most of the ones, fortunately, that you want to avoid too much are not allowed for sale to homeowners. That's a really, really good thing. 

What you want to make sure that you're looking at if if anyone is using any chemicals in the garden. Every single product has a label on it, and that label has to match whatever you're trying to to achieve, right? 

So If you're trying to eliminate cabbage worms, for example, in your garden. That label needs to say that that product will take care of cabbage worm. 

Otherwise you should not be using it whatsoever, and so we say this recommendation with any chemical, but also all of those home remedies that you hear about. We don't recommend using them because there's not that science to back it up that says this label identifies the cabbage worms. And cabbage worms are my identified problem so this is going to work. So that's one of the first things. 

00:24:45 Heather Zidack 

The other thing that's really important in making sure that you're monitoring regularly and looking for bugs. Because a lot of times if you can take care of the problem early, you don't necessarily need those chemicals. Or there could be other ways to manage it before you get to that point. So as soon as you see something, get a picture and we could help you or have someone at a garden center help you identify what's what's going on. And what you can do to treat it. 

00:25:14 Heather Zidack 

Reading that label is the most important thing that anybody can do, and it's the safest thing because you want to make sure you're doing targeted approaches to target species when you're using any chemicals in the garden. 

00:25:27 Stephen Thal 

Yeah. And also if you have a bug you're not familiar with, put it in a little container and send it up to you guys. 

00:25:35 Heather Zidack 

Yes, we can do that. We do insect identification-insects found in the garden. If, if they're found inside the home, we usually recommend like either a pest control expert or there's other resources available, but we are definitely able to do any garden pest. 

00:25:53 Stephen Thal 

Yeah. How about the got local garden clubs? Can they be helpful too? 

00:25:58 Heather Zidack 

Sometimes! They actually have some good resources. 

00:26:03 Heather Zidack 

If you're looking for an identification or a diagnosis, it really is good to come to the either the plant diagnostic lab or our office here because we have the connection to the diagnostic lab. But there are garden clubs. There are a lot of people with a lot of knowledge about gardening. The the reason that we we pride ourselves on is because we have a lot of research based information that we’re able to share with our clients. 

00:26:31 Stephen Thal 

Well, we want to thank you for coming in and sharing this vital information for getting your spring things started. 

00:26:40 Heather Zidack 

Thank you so much for having me. 

00:26:40 Stephen Thal 

And you know well, give us a call when the neck was a fall we have to get ready. 

Or. If there's any alerts, we can send them out. 

00:26:50 Heather Zidack 

Yes, I will let you know if there's anything else. 

00:26:55 Stephen Thal 

Well, I thank you very much, Heather, for coming on again. At the program we really enjoyed. 

I'm sure I got a lot out of it and I'm sure people here got a lot out of it. 

Appreciate you and your staff for all you do, why don't you give your number one more time? 

00:27:12 Heather Zidack 

Yes, if anybody has gardening questions for us, they can call and our number is 877-486-6271. Again, that's 877-486-6271. 

00:27:31 Stephen Thal 

OK, very , good. Thank you. Everybody thank you. 

Thank you for all you do to help make us a successful spring season. 

00:27:39 Heather Zidack 

Yes, thank you for having me. Have a good spring! 

00:27:41 Stephen Thal 

Like this is Steven Thal and another segment on focal point and we wanted to thank you the listeners for listening to all of the focal point programs. 

00:27:53 Stephen Thal 

As we mentioned earlier in the program, please wear your sunglasses and a hat because the sun is going to be a lot stronger this year because of climate changes. 

And also practice a family plan. If you don't know anything about it, contact a local fire department or go on the computer regarding emergency fire plans and involve everybody in in the House and doing a piece of it. And if you practice it a few times and also make sure that. Your fire alarm batteries or whatever are up to date cause a lot of them today are lasting 10 years. 

So get involved because life you say may be your own. 

00:28:36 Stephen Thal 

Thank you for allowing us into your homes. Safe and stay healthy. 

All-America Selection Winners for 2025

Posted on by

by Dawn Pettinelli, UConn Home & Garden Education Center

Each winter the All-America Selection winners are announced. This non-profit organization has established trial gardens throughout the United States and even as far north as Canada. New varieties, species or strains of annuals, vegetables and bedding plants are grown and judged on their performance. Those chosen as winners are outstanding plants and deserve a trial in your gardens as well.

This year’s national winners include 3 vegetables and 5 flowers. ‘Green Lightening’ is a very attractive, striped pattypan squash that tastes as good as it looks. The 5-inch or so fruits weigh in at 1 to 2 pounds and are ready to pick about 50 days after planting from seed. Judges marveled at the abundant yields on these 2 feet high, bushy plants.

Kohlrabi 'Konstance'
Kohlrabi ‘Konstance’ Image by all-americaselections.org

Kohlrabi ‘Konstance’ exudes a vibrant purple color as well as a sweet, crunchy texture. A curious but easy to grow and tasty addition to the vegetable garden, this kohlrabi matures at just 42 days from seed. Upright plants, about a foot high, produce round, purple 4 to 5-inch ‘bulbs’ that can be eaten fresh or served roasted or sauteed. Fruits are crack-resistant and plants resistant to several diseases.

Sweet pepper ‘Pick-N-Pop Yellow’ produces adorable, snack-size, extra sweet mini peppers. The pointed, conical fruits are about 4 inches long springing from compact 2-foot-tall plants. The prolific harvest begins about 65 days after transplanting. This variety shows great resistance to bacterial leaf spot.

One can never have too many dahlias and this year’s AAS winner, ‘Black Forest Ruby’ is a gem that can be started from seed. Since this variety is an octoploid (having 8 times the normal chromosome number) there is much variability in flower shape (ranging from single to double), plant height and structure. Most will be upright about 2 feet high with jet black foliage and ruby-red flowers. You can save tubers from the best-looking plants.

Dianthus ‘Interspecific Capitan™ Magnifica’ with its impressive bicolor pink and white frilly blooms looks as good in the garden as it does in a vase. Plus, the more you cut, the more blooms appear. Summer heat tolerance was impressive with the 2-inch flower heads also standing up to rain and cold. Plants range from 1 to 1 ½ feet tall and bloom all summer. Look for these vegetatively propagated plants at your local garden center.

Sunny sites will positively shimmy when planted with marigold Mango Tango. This rich red and primrose yellow bicolor blooms all summer long even without deadheading. Reaching only 8 to 10 inches in height makes it perfect for edging garden beds, containers or window boxes. Seeds can be started indoors and plants set out after the danger of frost has passed. Fertilize and water regularly for bountiful blooms.

Can there be too many petunias? ‘Petunia Shake™ Raspberry’ will convince you that there’s always room for one more. The fantastic flowers are reminiscent of a blended raspberry milkshake swirled with lemon-lime green sorbet. The 5 to 8 inch mounded plants can do front of the border duty, serve as groundcovers or billow over hanging baskets. Plants will bloom about 70 days from seed and hold up to heat and rain.

Snapdragon Double Shot Yellow-Red-Heart
Snapdragon‘DoubleShot™ Yellow Red Heart’Image by all-americaselections.org

I’ve never thought of snapdragons as fragrant, yet ‘DoubleShot™ Yellow Red Heart’ is said to have an amazing candy-like scent. Aside from this unusual trait, Yellow Red Heart promises to delight with vibrant yellow blossoms with a red throat that start early and continue through to a heavy frost. This snapdragon reaches about 20 inches in height with semi-double 1 to 1 ½ inch blooms produces all season long and able to tolerate light frosts.

Four regional 2025 Ornamental Winners well suited to the Northeast, include one petunia and 3 nasturtiums. If you’re looking for a vibrant pink petunia great for bedding and containers, try ‘Dekko™ Maxx™ Pink’. The vibrant pink 1 to 1 ½ inch starry blooms are produced all season long and hold up well to rain and heat.

Nasturtiums are top performers in garden beds and containers and are noted for their hummingbird attraction and edible leaves and flowers. New colors in the Baby series of nasturtiums to try out this year might be ‘Baby Gold’, ‘Baby Red’ and ‘Baby Yellow’. All can be grown from seed and start blooming about 50 days after sowing.
