bubba Posted January 30 Report Share Posted January 30 Articles on the Internet range from the opinion that Ceylon cinnamon (Cinnamomum vera, formerly C. zeylanicum) cannot be grown outdoors in southern California and South Florida (see Logee’s) to that it is a relatively easy to grow zone 9-11 sub-tropical. Dave’s Garden confirms this opinion and lists areas of outdoor growth from California, Arizona, Texas, and Florida. In one article, there is a recent picture (4/4/2022) of what appears to be a large specimen of Ceylon cinnamon at the San Antonio Botanical Garden (inside a pavilion?). I believe that San Antonio recorded a low temperature of 9°F in the February 2021 freeze. My guess is that different varieties of cinnamon have different cold tolerances, but I am not certain. A variety of cinnamon, referred to as wild cinnamon, is said to be limited to the west Indies. It is also said to grow in the Florida Keys and throughout Florida zone 10 B. Does cinnamon grow outdoors in your region? If so, can you post a picture of your specimen, and give an opinion of the variety and its cold tolerance?
