Guide

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

Aeonium arboreum is a succulent subshrub from the Canary Islands and Morocco, storing water in its fleshy rosettes and gritty-loving roots. Give it bright sun and fast-draining, mineral mix, and water only when the soil has dried out completely several inches down — it tolerates drought far better than wet feet. Expect it to slow or shed lower leaves during summer dormancy, which is normal rather than a sign to water more.
