About Dioscorea
Dioscorea, the yams, is a genus of the family Dioscoreaceae with more than 600 species in tropical and warm temperate regions worldwide. They are twining herbaceous vines with underground tubers, heart-shaped leaves and small flowers, and most species are dioecious; some produce aerial bulbils in the leaf axils. The genus includes edible yams such as D. japonica and D. polystachya, while the raw tubers of many species are toxic. In horticulture the South African D. elephantipes, with its cracked, tortoise-shell caudex, is grown as a winter-growing caudiciform succulent.
A winter-growing caudiciform vine with a large, partially exposed tuber covered in thick, corky plates resembling a tortoise shell. The tuber can reach over 1m in diameter and height in habitat. Produces annual climbing stems with heart-shaped leaves during the cooler months, dying back in summer. Dioecious with small greenish-yellow flowers.
