Guide

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

Alocasia longiloba is a rhizomatous geophyte from the tropical understory of Sulawesi, so it wants warmth, steady humidity, and bright indirect light rather than direct sun. The rhizome stores water and rots if left sitting wet, so let the top inch of mix dry before watering again. Provide a fast-draining mix and good airflow to keep the roots and storage organ healthy.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

Araceae contain insoluble calcium oxalate crystals, which irritate mouth and digestive tissue if chewed. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
