About Cape Clubfoot

Pachypodium bispinosum · also called Cape Clubfoot, Twin-spined Thick-foot · tropical

A South African caudiciform native to the rocky scrub of the Eastern Cape, forming an impressive partially buried caudex up to 60 cm across with wiry, spiny branches bearing small leaves. Produces charming bell-shaped pink to purple flowers in spring and summer. More cold-tolerant than its Malagasy relatives. Requires bright sun, sharp drainage, and very little water in winter.

Preferred mix: Gritty, fast-draining cactus mix

Watch for — Caudex rot: The main risk, caused by excess moisture at the caudex base or in cool soils. Always position the caudex at or above soil level, use extremely well-draining substrate, and reduce watering sharply in autumn.
