[11][12], Given their genetic differences forming distinct clades, Chinese Assam type tea (C. s. var. Fresh leaves contain about 4% caffeine, as well as related compounds including theobromine. Camellia sinensisis grown as a cash crop in plantations at high altitudes in East Africa. Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. C. s. var.

Our Silver Needle is unique in that it is sourced from Menghai and Mengku broad leaf varietal ancient tea tree groves in the remote, mountainous Yunnan Province of China. Camellia sinensis (L.) Kuntze Tea is a shrub grown to produce a beverage made from its leaves. assamica are two major varieties grown today. Caffeine, a molecule produced in C. sinensis, functions as a secondary metabolite and acts as a natural pesticide: it can paralyze and kill predator insects feeding on the plant. The Sinensis variety is a native Chinese plant, while Assamica has been found in the Indian province of Assam, after which it was named. However, since no wild populations of this tea are known, the precise location of its origin is speculative. Origins Camellia sinensis (or tea plant) is used to make most traditional caffeinated teas, including black tea, white tea, oolong tea, and green tea. waldenae was considered a different species, C. waldenae by SY Hu,[22] but it was later identified as a variety of C.

What is Tea? [20][21] Many high quality teas are grown at high elevations, up to 1,500 m (4,900 ft), as the plants grow more slowly and acquire more flavour. Carl Linnaeus chose his name in 1753 for the genus to honor Kamel's contributions to botany[5] (although Kamel did not discover or name this plant, or any Camellia,[6] and Linnaeus did not consider this plant a Camellia but a Thea).[7]. [27][28] The biosynthetic pathway in C. sinensis differs from other caffeine-producing plants such as coffee or guayusa. The astounding variety of teas available today, and the vast geography where tea is grown, is all the more amazing given tea’s early roots. assamica (Masters). The first is very suitable for green and oolong teas, while the second is usually used for black and fermented teas. Moving towards ‘Camellia Sinensis’ In 1818, English botanist Robert Sweet “grouped the various species of Thea under the heading of the genus Camellia.” Six years later, in 1824, Swiss Botanist Augustin Pyrame de Candolle “grouped the genus Thea within the order Camelliae.” The Camellia sinensis may be 12 m tall, but is cultivated low © Giuseppe Mazza The plant is native to Cambodia, China (Guangdong, Guangxi and Yunnan), India (Assam), Laos, Myanmar, Thailand and Vietnam, where it grows in the broadleaf forests up to 2.000 m of altitude in tropical and subtropical humid climate zones. Most tea regions experience three or four distinct flushes within each crop year. The leaves are glossy green with serrated edges and are similar in both shape and size to a bay leaf. The main attribute by which a tea is put into one of the six categories is its degree of polyphenolic oxidation.
