Pachypodium succulentum, the dikvoet (thick foot) in Afrikaans, is a slow-growing stem succulent growing from a large tuber. The tuber is partly underground and may reach 25 cm in diameter. The plant itself may grow to 2,5 m although this probably happens rarely, being commonly described as a shrublet.
The dikvoet occurs in the Great Karoo, the Little Karoo and dry inland parts of the Eastern Cape. The plant is quite variable in appearance and has been described in the past under names including P. griquense (a small form of it) and P. jasminiflorum (a white flowering variety); all of which are now regarded as belonging to the same species.
P. succulentum can be grown from seed or cuttings. It should be watered in summer (given where it comes from) and positioned in full sun or semi-shade. It may rot if over-watered (www.cactus-art.biz).
