Wisteria is a perennial vine native to both Japan and America. While Japanese wisteria can grow as much as 50 feet tall and can take years before it blooms, American wisteria is much more restrained, growing 15-25 feet, and its flowers appear at a much earlier age. The hardiest wisteria is a fast-growing, twining, deciduous vine that requires partial shade to full sun and needs regular watering especially in very hot weather. ‘Amethyst Falls’ blooms from May through August producing bluish lavender racemes 8-12 inches long. Grow it on a support either in the ground or in a container.
May - June, July - August
