American Wisteria (Wisteria frutescens)
Legume FamilyAmerican Wisteria is a deciduous, twining vine native to the southeastern United States. It produces racemes of fragrant, bluish-purple flowers in late spring to early summer, with occasional reblooming into late summer. It flowers on new wood, so seasonal pruning is recommended for more vigorous flowering and to keep the vine in check. American Wisteria typically grows 15–30 feet in length and needs a strong trellis or tree to climb on. For best flowering, plant it in a location with at least 6 hours of direct sun. It prefers moist soils but is adaptable to a variety of conditions, including clay and seasonally wet sites, once established. Its shorter flower clusters (4–6 inches), smooth seed pods, and clockwise twining habit help distinguish it from Asian species, which grow more aggressively, bloom earlier, and produce much longer flower racemes. American Wisteria also leaves out before flowering, unlike the invasive species that flowers before producing leaves.
