Wisteria frutescens (L.) Poir.
American Wisteria, Texas Wisteria, Kentucky Wisteria
Fabaceae (Pea Family)
Synonym(s): Kraunhia frutescens, Kraunhia macrostachya, Wisteria frutescens var. macrostachya, Wisteria macrostachya
USDA Symbol: wifr
American wisteria is a high-climbing woody, deciduous vine, 25-30 ft. long. Shiny, dark-green, pinnately compound leaves bear 9-15 leaflets which are opposite on the leaf stem, with 1 leaflet at the tip. The flowers are in large, drooping clusters 6-9 inches long that appear after the plant has leafed out, a difference from the popular Asian species. The blooms only appear on new wood. Individual flowers are nearly 1 inch long and are lilac or bluish purple and quite fragrant. A brown, bean-like pod persists until winter. This species is less aggressive than the similar Asian species.
American wisteria is often used as an ornamental planting and has probably escaped from cultivation in many locations. In Texas, the 'Dam B' cultivar has blue flowers in racemes and flowers late May to June and sporadically throughout the summer and fall. A cultivar called 'Nivea' has white flowers.
