American Wisteria is a woody, deciduous perennial vine that is not invasive like the Asian Wisteria. The blooms of cultivar 'Amethyst Falls' are said to be fragrant, but I find the scent rather unappealing. Here in my area the bloom time is extremely short, but I still enjoy the beauty of the flowers each spring.

American Wisteria (Wisteria frutescens) 'Amethyst Falls' produces deep lavender blossoms in late spring to early summer, with a rebloom in late summer. A native to eastern North America, 'Amethyst Falls' is a profuse bloomer and grows to about 8-10 feet long. It grows more slowly than its Asian counterparts, and does not damage buildings. Wisteria frutescens is a larval host plant for the Marine Blue Butterfly and several Skipper Butterfly species, including, Silver-spotted, Horace's Duskywing, Zarucco Duskywing, and the Long-tailed Skipper. Its blossoms have a sweet, musky fragrance.

'Amethyst Falls' is the most common cultivar sold in southeast PA of the American Wisteria, Wisteria frutescens. Like the straight species, this cultivar produces the flowers after the foliage emerges, does most of its blooming in late May-June, and does some additional blooming in July & August on the current year's growth.

'Amethyst Falls' is an "improved" selection of the native American Wisteria. It has longer and deeper purple flower clusters and it also flowers as a younger plant. It is equally as fragrant and as obedient as the other American Wisterias.
