Now that the holidays are over, the decorations are put away and scenes of dreary, wintry weather dance in our heads, one plant with flowers resembling roses that comes into bloom this time of year are camellias. These Asian natives have been cultivated for possibly 5000 years. Most of us are familiar with Camellia sinensis var. sinensis aka, tea! Black tea, white tea, green tea all come from the same plant just processed differently.  

 Other camellia species were noted and grown for their flowers gracing gardens of temples and nobility. Prized plants were selected and crossed and eventually made their way to England, sometime in the 1730s. These elegant and highly treasured plants soon were spread all over Europe with hybridists and propagators in Italy, France, Belgium, Holland, Portugal, Spain, Germany and the U.K. by the middle of the 19th century. More and more hybrids and cultivars were being developed with the number now well over 3,000. As their popularity grew, camellias were soon being grown in Australia, New Zealand and the U.S. Societies, like the American Camellia Society sprang up and shows were held (and still are) to exhibit various forms and compete for awards.

Options for growing camellias in Connecticut depend on what part of the state you live in. Thanks to breeding efforts of Dr. William Ackerman (retired USDA plant breeder) and Dr Clifford Parks (Univ of NC botanist) varieties of camellias hardy to zone 6 (-10 F) were developed. Depending on the variety and environmental conditions, camellias can bloom from fall to spring. Many of the most popular cold hardy, fall blooming cultivars belong to the Winter Series bred by Ackerman and include plants such as ‘Polar Ice’, Winter Charm’ and ‘Winter Rose’, the latter reaching only 2 to 3 feet high and wide making it a possibility for container culture.  

 Dr. Parks focused on cold hardy spring bloomers including the April series (C. japonica hybrids). Many grow from 5 to 10 feet tall and can be found at some local nurseries. Look for ‘April Rose’, ‘April Blush’, ‘April Remembered’ and ‘April Tryst’.   

Keep in mind that our weather has been somewhat unpredictable so those in zone 6 might want to locate plants in a semi-shaded, protected location. Camellia flowers are just exquisite, resembling roses in colors ranging from white to pink to red. Some are picoteed, some are double and some are very fragrant. The dark green foliage holds up year-round.  

Camellias, being broad-leaved evergreen shrubs, have similar requirements to rhododendrons. They do best in an acidic, well-drained soil amended with organic matter. It is often best to group them for effect and also for some protection from the elements. Plants are slow-growing and need adequate moisture but avoid planting them in poorly drained sites. Semi to full shade is preferable as the leaves may scorch in sunny, dry areas. A fertilizer for acid-loving plants can be applied in early spring as directed on the package. Pruning is rarely needed but could be done right after flowering.  

I’ve never been fortunate to live in a warm enough location to plant camellias outdoors, but several cultivars are perfect as house plants if kept in a cool spot indoors. Two available from Logee’s in Danielson are ‘High Fragrance’ with delightfully scented light pink semi-double flowers and ‘Scentuous’ with fragrant, semi-double white blossoms. They have others blooming in their greenhouse.  

Growing camellias in containers is a splendid way to get winter color, often along with fragrance. According to Logee’s co-owner and horticulturist, Bryron Martin, plants require an acid soil with a pH around 4.8 to 5.8. They can be grown in a camellia/azalea potting mix. Martin advises that young plants can be pinched back for fuller growth although that will delay flowering a bit. Keep in mind that some cultivars can get up to 6 feet in height so either select those that mature at a smaller size or be sure you have space to accommodate them.   

Temperature is key to induce blooms. Ideally Martin recommends nighttime temperatures no higher than 59 F during the winter and preferably 30 – 40 F so an unheated room or sun porch is a great place for camellias. If nighttime temperatures are too high, the buds will drop. An east or west exposure will provide adequate light.  

Fertilize camellias in the spring when active growth begins. Use a fertilizer for acid loving plants as directed. Commercial synthetic and organic camellia fertilizers are available. Some growers use a cottonseed meal/bloodmeal homemade blend. To supply adequate magnesium to plants, Martin recommends dissolving 1 tablespoon of Epsom salts in a gallon of water and applying this mixture twice a year.  

For late fall through spring blossoms, indoors or out, camellias are attractive, evocative plants that perhaps more folks might consider cultivating. Those looking for a Valentine’s Day activity might consider the Camellia Festival at Planting Fields in Oyster Bay, NY. The Lyman estate in Waltham, MA also has a camellia greenhouse that is open to the public.
