Dioscorea elephantipes is a deciduous climbing plant known for its massive, partially buried tuberous stem (caudex) resembling an elephant's foot. The caudex grows slowly, often reaching over 3 meters in circumference and nearly 1 meter above ground, covered with thick, corky plates. It produces slender, leafy climbing shoots in winter with dark-spotted greenish-yellow dioecious flowers. The plant's starch-rich tuber and unique growth pattern make it a distinctive succulent-like specimen.
