(96-120” tall x 48-72” wide) If you adore the fragrant blooms of Wisteria, but want to avoid rampant invasive varieties, ‘Amethyst Falls®’ American Wisteria is the right choice for your garden. A preferred choice to the Japanese and Chinese varieties that have become invasive in some areas, 'Amethyst Falls®' is a cultivar of North American native wisteria. This variety blooms on new growth with tightly clustered lavender panicles in mid-spring, then again in late summer. Prune in late winter or early spring to encourage new growth. While some Wisteria can take up to 5 years to bloom, 'Amethyst Falls®' is known to bloom within the first couple of years. Its growth is manageable, at about one-third of the rate of Asian wisteria, though it can grow 10-15 feet in a year. The deep green foliage is a perfect foil for the 4-6” fragrant panicles that attract all manner of pollinators. A host plant for the Marine Blue butterfly, Silver-spotted shipper, and Long-tailed shipper. Once established in a full sun to part-shade site, 'Amethyst Falls®' American Wisteria is drought tolerant, however, it does best in well-drained moisture-retentive soils.
