Guide

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

A succulent subshrub from Mexico and Guatemala, Sedum mexicanum stores water in its fleshy leaves and wants gritty, fast-draining mix and plenty of bright light, including some direct sun. Water deeply but infrequently, only once the soil has dried out completely and the leaves begin to feel slightly soft. It rots quickly if left sitting in wet mix, so err toward keeping it dry.
