The wisteria is known for its stunning flowers (long, cascading racemes and are usually blue or purple). These grow in the spring once the tree is over about 12 years old. Leaf size can be reduced, but the flowerings can’t, sometimes leading to out-of-proportion trees; a Wisteria does best as a relatively large sized Bonsai.
For Bonsai purposes, the most commonly used Wisteria is the Floribunda (Japanese Wisteria) and the Sinensis (Chinese Wisteria).

Specific Bonsai care guidelines for the Wisteria
Position: Lots of light, preferably much direct sunlight, doesn't like much shade. Protect the root system during the winter.
Watering: Water relatively often, as the Wisteria Bonsai prefers lots of water, especially when flowering.
Feeding: Apply fertilizer in early spring, but reduce feeding once its flowers start growing.
Pruning: Style the tree once the blooms have gone by. Regular pruning is required to increase finer branching, but do not prune the tree if you want it to flower strongly.
Repotting: Repot young trees every year, older trees every second year, using a basic Bonsai soil mixture. The root system can be pruned back aggressively.
Propagation: Use cuttings (in summer) or layering.
