This climber is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring. Position: full sun or light, dappled shade; Soil: fertile, moist, well-drained soil; Rate of growth: fast-growing; Flowering period: May to June; Hardiness: fully hardy Pendent clusters of lighly fragrant, double, pea-like, violet-blue flowers with white and yellow markings in May and June. This vigorous wisteria is perfect for training over a sunny wall or a stout pergola. To enhance flowering it requires ample space for the roots to ‘run’ and pruning rigorously twice a year. This plant has been vegetatively propagated, so will flower earlier than those grown from seed; Garden care: To get lots of flowers, the twining stems need pruning twice a year – once in summer (about two months after the flowering has finished) and again in mid-winter. In summer, cut back the wispy stems on both the laterals and sub-laterals (the side shoots from the laterals) to about five or six buds from the main branches. In winter, cut back these stems even harder to within two or three buds of the main branches. These form the short spurs that will go on to produce flowers in the following spring.
