5 Seeds Dioscorea oppositifolia Chinese Yam Climbing Vine Tropical Edible Heirloom

Dioscorea oppositifolia, commonly known as Chinese yam, is a twining herbaceous vine grown for its slender, edible tubers and lush heart-shaped foliage. It produces vigorous climbing stems that can quickly cover a trellis, arbor, or fence, adding a tropical look and vertical interest to warm-climate gardens.
This vine works well as an ornamental climber on supports and as a food garden crop where the tubers are harvested for cooking. It prefers a sunny position with consistent moisture and room to climb, and the twining growth habit means it will need a trellis or similar structure to scramble up.
