Wisteria is a large, deciduous climber that produces stunning, fragrant flowers of mauve or white throughout May and into June.
It prefers a sunny location with well-draining soil. Whilst it will tolerate partial shade the plant will produce fewer flowers. The branches become quite heavy over time so needs a surdy support system on which to climb.
Wisteria is a hardy plant but does best in a sheltered spot. It prefers a slightly acidic soil which is well drained. Whilst water-logging can lead to root rot it may need watering in dry periods especially if you have sandy soil. When newly planted it can take up to 3 or 4 years before flowers are produced.
To ensure plenty of flowers, and keep it under control, pruning is key. In late summer shorten the long, whippy growths. Then in late winter/early spring prune it back to a framework, shortening the side-shoots to a couple of buds. Left to their own devices wisteria can grow to 10m.
