Most varieties derive from the Chinese Wisteria sinensis and from the Japanese Wisteria floribunda.

Varieites

Wisteria floribunda ‘Alba’

Or consider Wisteria f. Multijuja’ which can produce spectacular long trusses up to 1m. with mauve flowers.

Pruning

How to prune wisteria. A mature wisteria needs to be pruned twice a year to keep the growth under control and to promote flowers.

Summer pruning wisteria

Cut back the current season’s long soft growth to about 15-20cm from the main branches in late summer (July-August) or to within five to six leaves.

Winter pruning wisteria

Cut back all the summer-pruned sideshoots to two or three buds in mid-winter.

After flowering, a wisteria can produce green bean-like seed-pots. Cut them off, or leave the seed-pots on for winter interest.

How to grow

Add plenty of compost to the planting hole before planting a wisteria. Compost keeps the moisture in the soil.

Support. Wisteria is a very strong grower and a mature plant will develop a lot of weight. Choose sturdy support that is capable of supporting the mass of the woody stems.
