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.

Carry out grafting or layering during the growing period.
Young plants may also be transplanted during the dormant period.

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.

Note
Care should be taken when planting as mature plants produce strong thick stems.


Botanic information
Leaf: The pinnate leaves have 7 to 13 ovate-lanceolate leaflets that are up to 100mm (4in) long. The apex is acuminate and the base is broad cuneate. Young leaves are bright green, ageing to dark green then turning yellow in autumn before falling.

Flower: The fragrant papillionate flowers are arranged in a pendant raceme that is up to 300mm (12in) long and are smaller than Wisteria floribunda. The blue to lilac flowers appear on mass before the leaves during spring.

Fruit: The velvety brown pod is slender and woody and bursts open when ripe and contains 1 to 3 seeds. The small seeds are viable but the plant is commonly reproduced vegetatively.
