Sinensis is a deciduous twining shrub with fresh-green pinnate leaves. It is so named because of its abundant, full flowers produced on bare stems in spring. The flowers are blue-violet, highly scented, in drooping racemes and pea-like, often produced in the first or second year after planting.
After planting prune back the leading shoot to 90cm (36in) above the ground. In the first growing season tie in lateral shoots and cut back sub-lateral shoots to two or three buds. During the first winter cut back laterals by one third and sub-laterals by two or three buds.
Eventual Height: 9m
Eventual Spread: 5m
It can be grown traditionally on the wall of a large house, with wall nails used to hold the framework of main stems in place, or allowed to scramble through a big tree where it looks most spectacular as well as being maintenance free.
Like most wisterias this is slow to get established and may take several years to start flowering.
The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
The plant is grown in a 5 litre pot and is approx 4ft tall
