Royal Purple™ Japanese Wisteria

Royal Purple™ Japanese Wisteria is a named Japanese wisteria vine with long, deep-violet flower clusters and a sweet fragrance. Its twining stems need a strong permanent support and regular pruning to keep the display in its space. ### Placement and flowering Grow in full sun to partial shade, and plan for the vine to become large as it establishes. The exact cultivar profile describes early-spring flowers and yellow autumn foliage; flowering can vary with local climate.

The source advises training for the first three years, then pruning in spring after flowering. Its long, fragrant clusters make it a useful vertical accent where there is room for a woody vine. ## Maintenance Give the support a secure footing before growth thickens. Tie new stems in the direction you want them to travel, remove misplaced shoots, and prune after bloom each spring to control the outline. Wisteria seeds and pods should not be eaten; keep them away from children and pets. [RHS Wisteria profile](https://www.rhs.org.uk/plants/363930/wisteria-floribunda-kokury/details)
