Wisteria is a long-lived vining plant with cascades of blue to purple flowers that look spectacular hanging from a pergola or archway in spring and early summer. However, this vine is a fast and aggressive grower—often reaching 30+ feet long—and is known to grow quite heavy. Wisteria vines will work their way into any crook or cranny they can reach, so it’s advised to not plant them too near to your home.Wisteria flowers are beautifully fragrant, providing a feast for the senses. After flowering, a brown, bean-like pod stays on the plant until winter. Blooms only appear on new growth.
