Wisteria sinensis

Chinese Wisteria

The most common wisteria in the West. Leaves are 10–12 in. long, divided into 7–13 leaflets. Blooms before leafout. Clusters of violet-blue, slightly fragrant flowers are shorter (to 1 ft.) than those of W. floribunda but they make quite a show, since flowers open all at once nearly all along the cluster. Plants will bloom in sun or considerable shade.
