Botanical name: Dioscorea opposita
I planted the Dioscorea opposita in January 2015 and left it in a green plastic pot until today. The yield is not great (just over a kilo) but considering it was put aside almost totally neglected, I'm keen to grow this again with more TLC.
In China, Huai Shan tuber is a sought after product because of its claimed medicinal benefits. I grow this for my stir-fries, especially nice in soups. I find the colour of the creamy white flesh more appealing than the purple flesh of the dioscorea alata.
