Camellia sinensis
Benifuuki, Camellia sinensis, Camellia thea, Camellia theifera , ,Green Sencha Tea, Thé Vert Sensha, Thea bohea, Thea sinensis, Thea viridis, Yame Green Tea, Yabukita,
“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: 茶花; pinyin: Cháhuā, 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.
The name Camellia is taken from the Latinized name of Rev. Georg Kamel, SJ (1661–1706), a Moravian-born Jesuit lay brother, pharmacist, and missionary to the Philippines.
Carl Linnaeus chose his name in 1753 for the genus to honor Kamel’s contributions to botany (although Kamel did not discover or name this plant, or any Camellia, and Linnaeus did not consider this plant a Camellia but a Thea).
Camellia sinensis is native to East Asia, the Indian Subcontinent and Southeast Asia, but it is today cultivated across the world in tropical and subtropical regions.
Camellia sinensis is an evergreen shrub or small tree that is usually trimmed to below 2 m (6.6 ft) when cultivated for its leaves. It has a strong taproot. The flowers are yellow-white, 2.5–4 cm (0.98–1.57 in) in diameter, with 7 to 8 petals.
The seeds of Camellia sinensis and Camellia oleifera can be pressed to yield tea oil, a sweetish seasoning and cooking oil that should not be confused with tea tree oil, an essential oil that is used for medical and cosmetic purposes, and originates from the leaves of a different plant.
The leaves are 4–15 cm (1.6–5.9 in) long and 2–5 cm (0.79–1.97 in) broad. Fresh leaves contain about 4% caffeine, as well as related compounds including theobromine.”
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 clonal one is commercially cultivated from the equator to as far north as Cornwall and Scotland on the UK mainland.
Potent antioxidant , best not to consume however at alkaline (pH 13) conditions as it then becomes a pro-oxidant (Excerpt from research:” The maximum extractable polyphenols and flavanoids were achieved at 6–8 min after the tea brew is prepared. “) *see research link PMC3679539/ , /PMC4520228/
