American wisteria

Wisteria frutescens

American wisteria (Wisteria frutescens) is a vigorous, deciduous, woody climber. Its large fragrant flowers come in shades of white, pink, lavender, and blue. It produces long, sprays of fragrant, pea-like flowers in late spring or early summer before the foliage. The foliage is mid to dark-green, composed of 9-13 leaflets. It grows and climbs by twining its stems around available structures or other plants. A fast growing plant, American wisteria is drought tolerant and can be pruned for a more manageable size. In USDA plant hardiness zones 5-9, it is an excellent choice for training around arbors, pergolas, trellises, and other structures.
