White Hyacinth Bean Vine Seeds – Lablab purpureus, Edible Ornamental Climber, 10–15 ft

A Fast-Growing, Beautiful Vine That’s Both Ornamental and Edible

White Hyacinth Bean Vine (Lablab purpureus) is one of the most vigorous and rewarding annual climbers you can grow — reaching 10–15 feet in a single season with a profusion of delicate white flowers that attract butterflies from summer through fall. A beloved food crop across India, Africa, and much of Asia, the young pods can be sliced or used whole in curries, stews, and stir-fries. Beautiful on a trellis or fence, productive in the garden, and rich in cultural significance around the world.

⚠ Important Safety Note: Hyacinth beans contain naturally occurring cyanogenic glucosides. Never eat raw hyacinth beans. Always cook pods and beans thoroughly — heat neutralizes the cyanogenic compounds. Keep raw beans away from children and pets.

In the Kitchen

Young pods (up to 3" long) can be sliced or cooked whole in curries, dals, stews, and stir-fries. They taste best slightly overcooked. Only young, tender pods are typically eaten — always cook thoroughly. The beans inside mature pods are not safe to eat raw.
