Guide

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

Pachypodium lamerei is a stem-succulent caudiciform that stores water in its thick, spiny trunk, so it tolerates drought far better than standing moisture. Give it the brightest, sunniest spot you can and gritty, fast-draining mix, then water deeply only once the mix has dried out completely — when the trunk feels firm and the soil is dry well below the surface. Withhold water further in cool or dim conditions, as a wet, cold root system will rot the caudex quickly.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

Apocynaceae commonly contain toxic cardiac glycosides and irritant latex. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
