Wisterias are beautiful twining climbers with pungent scented flowers in shades of white, purple and pink. Ideal for training into trees and covering walls, pergolas and other garden structures, the genus includes ten species of deciduous climbing vines, two native to the southern United States and the others native to eastern Asia. Two species of wisteria are typically grown in home gardens: Wisteria sinensis or Chinese wisteria, and Wisteria floribunda or Japanese wisteria.
