Amorphophallus macrorhizus

A Thai Amorphophallus from monsoon forest of the north and west, growing from an elongated rhizome-like tuber. It produces its leaf in the rainy season and goes fully dormant through the dry, cool winter, so it should be grown with a strict wet-season and dry-rest rhythm.
