Dioscorea Elephantipes Elephant's foot in a pot

It is a deciduous climber. It takes the name "elephant's foot" from the appearance of its large, partially buried, tuberous stem, which grows very slowly but often reaches a considerable size, often more than 3 m (10 ft) in circumference with a height of nearly 1 m (3 ft 3 in) above ground. It is rich in starch, whence the name Hottentot bread, and is covered on the outside with thick, hard, corky plates. It requires significant processing before being eaten to remove toxic compounds. Primarily a winter grower, it develops slender, leafy, climbing shoots with dark-spotted, greenish-yellow flowers in winter (May or June in habitat)[1] The flowers are dioecious, with male or female flowers occurring on separate plants.
