Guide

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

A succulent subshrub from Madagascar, Kalanchoe laxiflora stores water in its fleshy leaves and is adapted to bright, dry conditions. Give it the brightest spot you have, ideally some direct sun, and gritty, fast-draining mix. Water only when the soil has dried out completely, roughly every 10 to 21 days, since it rots far more easily than it goes thirsty.
