Camellia sinensis is a species of evergreen shrub or small tree whose leaves and leaf buds are used to produce tea It is of the genus Camellia. (Chinese: Camellia; pinyin: Cha hua, literally: "tea flower") of flowering plants in the family Theaceae. Common names include "tea plant", "tea shrub", and "tea tree" (not to be confused with Melaleuca alternifolia, the source of tea tree oil, or Leptospermum scoparium, the New Zealand teatree).
Two major varieties are grown:. Camellia sinensis var sinensis for Chinese teas, and Camellia sinensis var assamica for Indian Assam teas  White tea, yellow tea, green tea, oolong, pu-erh tea and black tea are all harvested.. from one or the other, but are processed differently to attain varying levels of oxidation. Kukicha (twig tea) is also harvested from Camellia sinensis, but uses twigs and stems rather than leaves.
This Chinese species is closely related to C. japonica, but it has larger flowers and can have a distinct orange-red hue in the flowers.The flowers are single with a large boss of yellow anthers and bloom from late winter into early spring. Reports from this country indicate this is species is quite cold-hardy, possibly into Zone 6. This is a showy species, which deserves to be used widely in the landscape and hybridized to push the limits of camellias. Often large apple-sized fruits are produced and the seeds can be pressed to make high-quality oil for cooking.
