Wisteria sinensis, commonly known as the Chinese wisteria, is a species of flowering plant in the pea family, native to China, in the provinces of Guangxi, Guizhou, Hebei, Henan, Hubei, Shaanxi, and Yunnan. Growing 20–30 m (66–98 ft) tall, it is a deciduous vine. It is widely cultivated in temperate regions for its twisting stems and masses of scented flowers in hanging racemes, in spring.
Wisteria sinensis clings to supporting plants or man-made structures by counterclockwise-twining stems. The leaves are shiny, green, pinnately compound, 10–30 cm in length, with 9-13 oblong leaflets that are each 2–6 cm long. The flowers are white, violet, or blue, produced on 15–20 cm racemes before the leaves emerge in spring. The flowers on each raceme open simultaneously before the foliage has expanded, and have a distinctive fragrance similar to that of grapes. Though it has shorter racemes than Wisteria floribunda (Japanese wisteria), it often has a higher quantity of racemes. The fruit is a flattened, brown, velvety, bean-like pod 5–10 cm long with thick disk-like seeds around 1 cm in diameter spaced evenly inside; they mature in summer and crack and twist open to release the seeds; the empty pods often persist until winter. However seed production is often low, and most regenerative growth occurs through layering and suckering.
All parts of the plant contain a glycoside called wisterine which is toxic if ingested and may cause nausea, vomiting, stomach pains, and diarrhea. Wisterias have caused poisoning in children of many countries, producing mild to severe gastroenteritis.
Wisteria sinensis was unknown in the west before 1816, when several agents of the East India Company working in China sent cuttings back to England. Over the next several decades the plant became, and remains, one of the quintessential ornamental vines in temperate gardens worldwide. A 200-year-old specimen, growing at Griffin's Brewery in Chiswick, London, is often cited as the UK's oldest living wisteria plant.
Introduced to the Botanical Garden. The seeds of this species were brought from China and sown in the Botanical Garden by academician F.N. Rusanov in 04/19/1954. In 1955, in the spring, the introduction of these species was sown in the nursery and studied, and in 11.15.1956 they were planted in the East Asian exposition. Currently, a liana of this species grows in this exposition for 2 adult years.
