The Vine That Blooms in Magenta and Purple

Few flowering vines put on a show quite like this one. Purple Hyacinth Bean climbs fast and covers itself in spikes of fragrant purple pea-like flowers all summer, followed by glossy, magenta-colored seed pods hanging in clusters just as showy as the blooms. It's a genuine pollinator magnet, drawing bees and butterflies through its long bloom season, and its speed and vigor make it one of the fastest ways to cover a trellis or fence with real color in a single season.

What This Fast-Growing Ornamental Vine Actually Is
Lablab purpureus, called purple hyacinth bean or lablab bean, is a fast-growing twining vine native to Africa, widely grown as an ornamental for its fragrant purple flower spikes and glossy, deep magenta seed pods. Vines climb rapidly to 10 to 20 feet in a single season, covering trellises, arbors, and fences with dense foliage and continuous bloom from summer into fall. The pods that follow are genuinely eye-catching, a vivid magenta-purple that holds color well even as they dry. While hyacinth bean is grown and eaten as a food crop in parts of the world, the raw pods and beans contain cyanogenic compounds and require extensive cooking to be safe; this variety is grown here as an ornamental, and the pods and beans should not be eaten. Grown as a warm-season annual in most climates, tender perennial in the warmest zones.
