Amorphophallus ongsakulii

The genus Amorphophallus is known for producing some of the largest, stinkiest inflorescences in the botanical world, so A. ongsakulii comes as something of a surprise when it sends up a thumb-sized spathe and spadix, from a plant with leaves just a few inches tall. The flowers have faint spicy sweet smell.

Amorphophallus ongsakulii's natural habitat is the understory of tropical rain forest in Laos. It was only described in 2006. For me, the plant has done quite well in a warm greenhouse with some shade, with a winter dormant period where the leafless tubers were kept potted in slightly moist soil.
