Wisteria Tree

Wisteria is a genus of vigorous, long-lived, fragrant-flowered climbers; its species differ in flower color, raceme length and flowering sequence. Most can be trained on a wall, pergola or arch, while a free-standing standard can be grown in a border or large container. ([RHS Wisteria genus guide](https://www.rhs.org.uk/plants/wisteria); [RHS growing guide](https://www.rhs.org.uk/plants/wisteria/growing-guide)) ## Garden use Choose a sunny wall or strong garden structure for a climber, or train it as a standard when a more compact outline suits the space. The RHS describes flowering in late spring, with occasional summer flowers; Japanese, Chinese and silky wisterias differ in raceme length and in whether flowers open before or with their leaves. Mid-green foliage turns yellow in autumn. ([RHS Wisteria genus guide](https://www.rhs.org.uk/plants/wisteria)) ## Growing conditions Plant in well-drained soil and full sun for the best flowering; light shade is tolerated but may reduce blooms. Water well during dry periods, especially while establishing and in sandy soil. Avoid sites that stay waterlogged or are deeply shaded.

Provide sturdy support for climbing stems. ([RHS pruning guide](https://www.rhs.org.uk/plants/wisteria/pruning-guide))
