'''''Wisteria sinensis''''' ('''Chinese Wisteria''') is a [[Woody plant|woody]], [[deciduous]], [[Perennial plant|perennial]] climbing [[vine]] in the genus ''[[Wisteria]]'', native to [[China]] in the provinces of [[Guangxi]], [[Guizhou]], [[Hebei]], [[Henan]], [[Hubei]], [[Shaanxi]], and [[Yunnan]]. 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.
It can grow 20-30 m long over supporting [[tree]]s by [[counter-clockwise]]-twining stems. The [[leaf|leaves]] are shiny, green, [[pinnate]]ly compound, 10-30 cm in length, with 9-13 oblong [[leaflet]]s that are each 2-6 cm long. The [[flower]]s are white, violet, or blue, produced on 15-20 cm racemes in [[Spring (season)|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 [[grape]]s. Though it has shorter [[raceme]]s than ''[[Wisteria floribunda]]'' (Japanese Wisteria), it often has a higher quantity of racemes. The [[fruit]] is a flattened, brown, velvety, bean-like [[legume|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]]. One very interesting fact about this plant is that it is actually a member of the pea family, and the abovementioned seedpods are actually legumes.
It is [[Hardiness (plants)|hardy]] in [[USDA plant hardiness zones]] 5-9, 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 (organism)|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. It has however become an [[invasive species]] in some areas of the eastern [[United States]] where the climate closely matches that of China.
