ABSTRACT
Wisteria is a genus of seven to ten species of deciduous twining climbers. Two species (W. frutescens L. and W. macrostachya [Torr. and A. Gray] Nutt. ex Torr. and A. Gray) are native to North America, while the others are from China or Japan. Wisteria belongs to the family Leguminosae. 2 In horticulture, the plants are grown for their long racemes of attractive flowers which bloom in the spring. Frequently, the vines are allowed to grow on walls or on a trellis support over a walkway for the display of the long, colorful racemes. The twisting of branches around supports provides a dense shade during the summer and an attractive effect when the leaves are not on the vines during the winter. Two species, W. floribunda (Willd.) DC. and W. sinensis (Sims) Sweet are the most commonly grown.
