Tea (Camellia sinensis) is an evergreen shrub or small tree grown commercially for its leaves, which are made into green, black, oolong and other teas. Plants grow best in rich, moist, well-drained soil with plenty of rain and are usually pruned to waist height on plantations.

About

Camellia sinensis, commonly known as tea plant, tea shrub, and tea tree, is a species of evergreen shrub in the flowering plant family Theaceae. The leaves harvested from C. sinesis are brewed into tea.

Originally native to the highlands of the Hengduan–Purvanchal region between southwestern China, northern Myanmar and northeastern India, the leaves, buds and stems of C. sinensis are harvested by humans to produce tea, leading to its artificial introduction and cultivation as valuable cash crops in many other parts of the world, with China, India and Kenya being the three largest tea-producing countries.

How to grow it

Camellia sinensis is mainly cultivated in tropical and subtropical climates, in areas with at least 127 cm (50 in) of rainfall a year. Tea plants prefer a rich and moist growing location in full to part sun, and can be grown in hardiness zones 7–9. However, the species is commercially cultivated from the equator to as far north as Scotland, with the northernmost tea plantation at 59°N latitude on Shapinsay in the Orkney Islands. Many high quality teas are grown at high elevations, up to 2,200 m (7,200 ft), as the plants grow more slowly and acquire more flavour.

Tea plants will grow into a tree if left undisturbed, but cultivated plants are pruned to waist height for ease of plucking. Two principal varieties are used, the small-leaved Chinese variety plant (C. s. var. sinensis) and the large-leaved Assamese plant (C. s. var. assamica), used mainly for black tea. Tea trees can remain productive for many years.

Where it grows

The origins of tea plants are obscured by their long history of cultivation. The natural range is unknown, though it is reasonably certain that the species comes from East Asia with the exact location being debated by experts.
