Widely esteemed for its delicate appearance, elegant sweetness and noble character, Silver Needle tea is comprised of pure, individually plucked tea buds harvested only in the early springtime. [10], Chinese (small leaf) type tea may have originated in southern China possibly with hybridization of unknown wild tea relatives. The seeds of C. sinensis and C. 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 glossy green with serrated edges and are similar in both shape and size to a bay leaf. It is in leaf all year, in flower from March to May. sinensis and C. s. var. Camellia flowers are very popular in the Far East, having at one time been called by botanist Engelbert Kaempher the “Japan Rose”. From this one species stems two main varieties known as Camellia sinensis var. dehungensis (Hung T. Chang & BH Chen) TL Ming are sometimes used locally. Extraction Solvent: Acetone & water (80:20) Diluent: 0.5% formic acid in water Test Sample Preparation: Transfer 1 g of ground plant material into a screw cap bottle, add 50 ml of Extraction Solvent, tightly cap, and shake for 4 h in a mechanical shaker at room temperature. 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].

The Sinensis variety is a native Chinese plant, while Assamica has been found in the Indian province of Assam, after which it was named. Assam tea is manufactured specifically from the plant Camellia sinensis var. sinensis: this province shows the greatest genetic diversity among the wild trees—the longer a species is present in an area the greater the chance to accumulate mutations, and the greater the differences among individuals of the present day populations. Species of flowering plant in the family Theaceae, "Tea plant" redirects here. As with apple trees and grapevines, cultivars with individual appearance and taste characteristics have arisen as a result … From its distant Chinese origins the taste for tea has crossed all borders.

The assamica or “broad leaf” variety most closely resembles the original tea plant, where as the sinensis or “small leaf” variety evolved as the tea plant was carried from its subtropical homeland to more temperate climates. The leaves are 4–15 cm (1.6–5.9 in) long and 2–5 cm (0.79–1.97 in) broad. Camellia sinensis, the tea camellia, flowering at the end of March With just one sizeable bush of the tea camellia, C. sinensis , the harvest was never going to be huge but after fiddly-faddling with a few minor efforts in recent years, I was determined to get as much as I could this year. [3] White tea, yellow tea, green tea, oolong, dark tea (which includes pu-erh tea) and black tea are all harvested from one or the other, but are processed differently to attain varying levels of oxidation. C. sinensis is mainly cultivated in tropical and subtropical climates, in areas with at least 127 cm (50 in) of rainfall a year. Camellia sinensis is a species of evergreen shrubs or small trees in the flowering plant family Theaceae whose leaves and leaf buds are used to produce tea. All other drinks made with flowers, herbs, fruits etc, must be called differently. Kukicha (twig tea) is also harvested from C. sinensis, but uses twigs and stems rather than leaves. lasiocaly) was originally considered a type of assam tea. It has a strong taproot. 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.” It is an evergreen shrub or small tree that is usually trimmed to below 2 m (6.6 ft) when cultivated for its leaves.

According to history, Camellia sinensis was first used as a medicine in the Chinese province of Yunnan. Thus, Western Yunnan Assam tea and Indian Assam tea both may have originated from the same parent plant in the area where southwestern China, Indo-Burma, and Tibet meet.

[17] The young, light-green leaves are preferably harvested for tea production; they have short, white hairs on the underside. Initial effort of planting Chinese varieties in Assam soil did not succeed. The first evidences of use and cultivation of camellia in China are about 5 000 years old. This natural oxidation is an enzymatic reaction that is similar to the browning of a sliced apple or freshly chopped basil leaves. The Camellia's origin. It is believed that these foundational uses of tea date back some four or five thousand years, making tea about as ancient as the primitive styles of wine and beer. Some Indian Assam tea appears to have hybridized with the species Camellia pubicosta. It is hardy to zone (UK) 8.
