1 pound from this wonderful Dioscorea bulbifera vine that I grow in pots on my patio. The leaves are 2 to 6 inches wide, very shiny, heart shaped and deeply veined. The flowers are produced in the fall and hang down with small white star-like buds and are very attractive. This plant is also known as air potatoes because they form small bulbs along the vines as they grow. They will form a vine for the patio and along a trellis or quick growth for a covered patio area. Zones 9 to 11.
