American Wisteria

American wisteria is a native vine from the eastern United States reaching 15-40 ft with rapid growth. It produces fragrant, pea-like lilac-purple or blue flowers in drooping racemes to 6 in. long, with some cultivars offering white, burgundy, or hints of yellow.

American wisteria is hardy in zones 5a-9b and grows in sun to part shade with moist to well-drained, acidic soil (pH below 6.0). Growth is rapid with medium maintenance. It is toxic to cats, dogs, and horses. It attracts birds and is useful for arbors and trellises.
