Guide

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

A succulent biennial subshrub from Madagascar, its fleshy leaves store water so it tolerates drought far better than standing wet. Grow it in gritty, fast-draining mix and water deeply only when the top two inches of soil are fully dry. It takes bright light readily but can scorch in harsh, prolonged direct sun behind glass.

Toxic to cats & dogs

Kalanchoe (Crassulaceae) contain cardiac glycosides (bufadienolides) that are toxic to pets. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
