Guide

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

Thaumatophyllum undulatum is a climbing aroid in the Araceae, a habit that suggests it grows up through dappled forest light rather than open sun. Give it a bright spot out of direct rays and a chunky, free-draining mix that it can climb against. Let the top inch or two of mix dry before watering, as this group resents sitting wet at the roots.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

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