About Japanese Wisteria
Wisteria floribunda is a fast-growing climber in the Fabaceae family. It reaches around 9 m tall and 6 m wide at maturity, with deciduous foliage. Purple and blue flowers appear in spring.
Where to grow Japanese Wisteria
Japanese Wisteria suits cool-temperate and warm-temperate climates and grows best in full sun. It is frost hardy and shrugs off cold winters.
Soil & planting
Japanese Wisteria does best in loamy and free-draining soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Japanese Wisteria is regular, moderate watering. A feed in spring with a balanced fertiliser keeps growth strong. In its first year, water deeply once or twice a week to settle the roots in, then taper off as it establishes.
Pruning & care
Prune Japanese Wisteria after flowering to keep it compact and encourage the next flush of blooms. Overall it is high maintenance.
Using Japanese Wisteria in the garden
Japanese Wisteria earns its place for a feature or specimen planting, a shade tree, its fragrance and feeding bees and pollinators.
Companion planting & design
For a cohesive, low-care bed, pair Japanese Wisteria with other plants that enjoy the same regular, moderate watering and cool-temperate climate. Group three or five together for impact rather than dotting single plants through the garden.
Good to know
Note that it is toxic to cats and dogs, so site it away from pets that chew. All parts can be toxic if eaten, so keep it away from small children. It is thornless and easy to handle. Be aware it can self-seed or spread into bushland in some regions — check it is not a declared weed in your area before planting.
