Wisteria floribunda was introduced to Western gardens in 1830 but has been cultivated in its native Japan for centuries. It is a rampant, hardy, deciduous woody twiner. The spring blooms are long hanging clusters of fragrant pea-like flowers.

Wisteria grows and blooms best in full sun and well-drained soil, and sometimes takes several years to flower. Soil that is too rich in nitrogen may promote lots of leaves at the expense of flowers.

As you know, this is a large and vigorous plant. Japanese wisteria needs a sturdy arbor or trellis for support and regular pruning to keep it in bounds. It can be trained as a small tree by staking a shoot upright, removing side shoots and restraining the top shoots by pruning for several years until the stem is self-supporting. Prune away you can't hurt this plant.

Wisteria is listed as an exotic invasive in several areas including the eastern United States.
