'''Japanese wisteria''' (''Wisteria floribunda'') is a [[Woody plant|woody]] [[liana]] of the ''[[Wisteria]]'' family. It was brought from [[Japan]] to the [[United States]] in [[1860]] by George Rogers Hall. Since then, it has become one of the most highly romanticized flowering [[garden]] plants. It is also a common subject for bonsai, along with [[Wisteria sinensis]](Chinese wisteria)
The flowering habit of Japanese wisteria is perhaps the most spectacular of the Wisteria family. It sports the longest flower [[raceme]]s of any wisteria; they can reach nearly half a [[meter]] in length. These racemes burst into great trails of clustered white, violet, or blue flowers in early- to mid-[[Spring_(season)|spring]]. The flowers carry a distinctive fragrance similar to that of [[grape]]s. The early flowering time of Japanese wisteria can cause problems in [[temperate]] climates, where early [[frost]]s can destroy the coming years' flowers. It will also flower only after passing from [[juvenile (organism)|juvenile]] to [[adult]] stage, a transition that may take many frustrating years just like its cousin [[Chinese Wisteria]].
Japanese wisteria can grow over 30m long over many supports via powerful [[clockwise]]-twining stems. The foliage consists of shiny, dark-green, [[pinnate]]ly compound leaves 10-30cm in length. The leaves bear 9-13 oblong [[leaflet]]s that are each 2-6 cm long. It also bears numerous [[poisonous]], brown, velvety, bean-like seed pods 5-10cm long that mature in [[summer]] and persist until [[winter]]. Japanese wisteria prefers moist soils and full sun in [[USDA plant hardiness zones]] 5-9<ref name="growth">[http://www.monrovia.com/PlantInf.nsf/67f84a5ebda3df3a88256f9d006b9c7c/4589aa8f48a70bf58825684d007273ab!OpenDocument&Highlight=0,wisteria&Click=882568470064D136.77a6cc4887b5c2ab88256f0e007d62a5/$Body/0.2BA2 Growth Conditions]</ref>. The plant often lives over fifty years.
