Guide
The species-level account. Cultivar pages build on this and say where they differ.
Amorphophallus konjac is a tuberous geophyte in the arum family, growing from a large underground corm that stores its own water and drives a single seasonal leaf. Water only when the top two inches of mix have dried, and ease off sharply as the leaf yellows and the plant enters dormancy — the corm rots easily if left sitting wet, especially when leafless. Give it bright indirect light and gritty, free-draining soil.

Toxic to cats & dogs & humans
Araceae contain insoluble calcium oxalate crystals, which cause oral and gastrointestinal irritation if chewed or ingested. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
