Blooming in June on new growth, individual flowers are borne on long showy racemes and open as a lovely shade of dark lavender before fading. Summer Cascade™ is a beautiful flowering vine which can easily cover an arbor or pergola, creating a cool, shady place. Producing an interesting seed pod in late summer, this vine has lovely multi-season interests and is more reliably cold hardy than other wisteria. Discovered by Betty Matthews in White Bear Lake, Minnesota and given to the University of Minnesota, introduced in partnership with Bailey Nurseries, Inc.
