Guide

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

Aloe marlothii is a large succulent shrub or tree from the hot, seasonally dry grasslands and rocky slopes of southern Africa, where it stores water in thick leaves and endures long dry spells. Give it the brightest spot you have, ideally direct sun, and a gritty, fast-draining mix. Water deeply but infrequently, only once the soil has dried out completely through the pot — when in doubt, wait, as standing moisture rots the roots.

ToxicityAuthoritative · species

Toxic to cats & dogs

Saponins + anthraquinones (the latex) — vomiting, lethargy, diarrhoea. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
