This member of the Dioscoreaceae family originates from Asia, but has been brought around the world, first by Arab traders, later by other traders, and remain a popular crop. It was given this name by Carl Linnaeus in 1753. It will grow in a rich but drained soil with some to lots of water and some sun. The clusters of rhizomes can grow large and each reach up to 60 centimetres in some parts of the world. In other, they grow more like potatoes, reaching six centimetres each. The vines can reach ten meters, and the flowers are white to crème coloured. I doubt the single rhizome will last for many years, or if they appreciate to be exposed.

Dioscorea is named after Pedianos Dioscorides, a Greek physician if the 1st century A.D. The species means 'winged' for the fruits.
