One of the showiest vines - and most vigorous!
Wisteria sinensis is the ever-popular Chinese Wisteria with fragrant, lilac-blue flowers in racemes up to 7 1/2 inches long. Its blooms appear from late winter to early summer, depending on your climate, and adorn the vines for several weeks each year. A rapid, vigorous grower to 40 feet, it's perfect for creating a spectacular show on a pergola or against a garden wall.
These tough, drought-resistant vines require minimal care. Plant in a sunny location near a strong support, and prune after flowering and again in late winter if you wish to control its size. Wisteria are easy to train into standard or "tree" form, helping to keep them within bounds and creating a dramatic accent in any landscape. Just attach the trunk of the plant to a sturdy 5- or 6-foot stake and trim all but the topmost branches. The goal is to achieve a bushy top growth that is supported by the vine's trunk. Remove the stake once the standard is established. Wisteria will tolerate partial shade conditions, but it will bloom its best when exposed to full sun. Zones 3-9.
