Guide

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

A succulent subshrub from the arid Cape Provinces and Namibia, storing water in its stacked, fleshy leaves and resenting wet feet. Plant it in gritty, fast-draining mix and water deeply only when the soil has dried out completely, including the lower root zone. Give it the brightest light you can — a sunny windowsill with several hours of direct sun.
