(No reviews yet) Write a Review

TsukuneImo is a special variety of Dioscorea polystachya / opposita with rounded 'dumpling' shaped tubers. Dioscorea polystachya 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 polystachya 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.
