Guide

The species-level account. Cultivar pages build on this and say where they differ.

A succulent tree from the hot, seasonally dry savannas of southern and eastern Africa, storing water in its columnar stems and rotting easily if kept wet. Give it gritty, fast-draining soil and bright direct light, and water deeply only once the mix has dried out completely — let the top several inches go fully dry before watering again. Cut back further in winter, when the plant is dormant and needs very little.
