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.
