Guide

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

Zantedeschia albomaculata is a tuberous geophyte from KwaZulu-Natal, storing water in its tuber and prone to rot if kept soggy. Give it bright indirect light and a gritty, free-draining mix, and water only when the top inch or two of mix has dried. Expect a natural rest period when foliage dies back, during which it wants far less water.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

Araceae contain insoluble calcium oxalate crystals, an irritant if chewed. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
