Propagation
Take basal cuttings from the side shoots during late spring or semi hardwood cuttings in early summer and place in a protected environment with a bottom heat.

Graft or layer the plant during the growing period.
Young plants may also be transplanted during the dormant period.


Botanic information
Leaf: The imparipinnate leaves have 11 to 19 ovate-oblong to elliptical short stalked leaflets with an acuminate apex and a rounded base and are up to 100mm (4in) long. They are bright green when young, ageing to dark green and turning yellow in autumn before falling.

Flower: The fragrant papillionate (pea-shaped) flowers have a pedicel that is up to 25mm (1in) long. They are arranged in a pendent raceme that is up to 520mm (20in) long, appearing before the leaves on the previous season`s growth during spring.

Fruit: The velvety brown legume is slender and woody and bursts open when ripe. It persists on the plant throughout winter. The seeds are viable but the plant may be reproduced vegetatively in order to maintain true to type.

Pruning
Wisterias that are grown into trees or over natural structures require no training. When training over a structure prune back the leading shoot to 1 m long (3 ft) after planting and during the first growing season tie the lateral shoots to the structure. When dormant in the first season cutback of the lateral shoots by one third. Similar pruning should be carried out over the next two seasons to obtain correct structure and once this has been accomplished the vine will require a light prune during late summer.
