Euphorbia cylindrifolia subsp. tuberifera (live succulent)

Euphorbia cylindrifolia subsp. tuberifera (live succulent)

Family: Euphorbiaceae

It is a dwarf, low-growing cushion-forming succulent with a rosette of narrow, serpent-like stems arising from a short, central subterranean caudex. Among the the Madagascan euphorbias species this is perhaps the most caudiciform. Subspecies tuberifera, when grown from seed, forms a conspicuous rounded tuber that can grow to fist-size or larger.
