Camellia sinensis

Camellia sinensis is the tea plant, the plant species whose leaves and leaf buds are used to produce tea.  White tea, green tea, oolong and black tea are all harvested from this species, but are processed differently to attain different levels of oxidation. The name sinensis means Chinese in Latin. Older names for the tea plant include Thea bohea, Thea sinensis and Thea viridis. Camellia sinensis is native to mainland South and Southeast Asia, but is today cultivated across the world, in tropical and subtropical regions. It is an evergreen shrub or small tree that is usually trimmed to below two metres (six feet) when cultivated for its leaves. It has a strong taproot. The flowers are yellow-white, 2.5–4 cm in diameter, with 7 to 8 petals.
