5 Dioscorea opposita Bulbils, Tsukune-Imo form, cultivar 'Nara', round "dumpling" shaped tuber
TsukuneImo is a special variety of Dioscorea opposita with rounded 'dumpling' shaped tubers. Dioscorea opposita tubers typically grow straight and deep into the soil, along with their brittle roots it can be a lot of work to harvest the tubers, requiring the excavation of a large hole. TsukuneImo varieties make harvest easier. Often these alternative tuber forms of Dioscorea opposita do not produce many bulbils. This is a cultivar 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 improved Tsukune Imo shape developing.
