Guide

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

Nerium oleander is a tough, sun-loving woody shrub in the Apocynaceae family, well adapted to warm, dry conditions and gritty, fast-draining soil. Give it a bright spot with as much direct sun as you can offer, and let the top inch or two of mix dry before watering again. It tolerates drought far better than sitting wet, so water deeply but infrequently and never let the pot stand in water.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans & horses

Apocynaceae contain cardiac glycosides; all parts are highly poisonous if ingested and the sap can irritate skin. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
