Caroline Chinese Wisteria
Wisteria sinensis ‘Caroline’
Caroline Chinese Wisteria is a classic selection of the vigorous Chinese species, known for its long, fragrant clusters of lavender-blue flowers in spring. Like all Chinese wisterias, it is a fast-growing, powerful vine that requires a very sturdy support structure and committed annual pruning to control its size and encourage flowering.

A vigorous, fast-growing vine that can quickly cover large structures (25-30 ft+). It twines clockwise (right to left).
