'Amethyst Falls,' like other Wisteria, is a strong grower, reaching 30 feet or more. It is, however, not invasive like its Asian cousins. This native variety is less vigorous and easier to manage. 'Amethyst Falls' will bloom its first season with fragrant, vivid, blue flowers that appear in spring and repeat all summer. The many attributes of 'Amethyst Falls' include its deer and drought tolerance. This vine is a perfect choice for pergolas, trellises, fences, and arbors attracting butterflies to your garden all summer long.
