Camellia sinensis var assamica
C. sinensis var assamica, or what we call "assam-type", often take more of a tree- than shrub-form with large, dark green leaves. Vigorous growth provides abundant tips to harvest from and make excellent black teas. In Zone 7b, these plants will appreciate some protection from cold weather.
