Ichoimo form of Dioscorea opposita, 5 bulbils
Icho-imo is a special variety of Dioscorea opposita with tubers that fan out forming a shape resembling a ginko leaf. Dioscorea opposita roots typically grow straight and deep into the soil, along with their brittle roots it can be difficult to harvest the tubers, requiring excavating a large hole. Ichoimo varieties make harvest much easier. Often these alternative tuber forms of Dioscorea opposita do not produce many bulbils. This is a selection grown specifically for the edible tuber. Bulbils are clones, making them a great way to propagate these plants.
Plant bulbils in deep loose soil for the best chance of the ichoimo shape developing.
