Wisteria is a vining plant with cascades of colorful flowers that look spectacular hanging from a pergola or archway in spring. However, the vine is a fast and aggressive grower?often reaching 25 to 30 feet long?and is known to grow quite heavy. Wisteria will work their way into any crook or cranny their vines can reach, so it?s not advised to 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 wood.
