The Wisteria sinensis or Chinese Wisteria is a woody, deciduous, perennial climbing vine in the genus Wisteria, native to China. While this plant is a climbing vine, it can be trained into a tree-like shape, usually with a wavy trunk and a flattened top.
The Wisteria can grow 20-30 m long over supporting trees by counter-clockwise-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 in spring, usually reaching their peak in mid-May. The flowers on each raceme open simultaneously before the foliage has expanded, and have a distinctive fragrance similar to that of grapes.
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.
It is hardy in Europe plant and prefers moist soils. It is considered shade tolerant, but will flower only when exposed to partial or full sun. It will also flower only after passing from juvenile to adult stage, a transition that may take many years. It can live for over 100 years. All parts of the plant contain a glycoside called wisterin which is toxic and 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. It was introduced from China to Europe and North America in 1816 and has secured a place as one of the most popular flowering vines for home gardens due to its flowering habit.
