Plants are 5" - 7" tall in 4” plastic pots. With proper culture I expect these will flower in 2 - 4 years.
This species is native to central Sulawesi (Celebes), Indonesia. This species as with most Amorphophallus and Arisaema species are seasonally dormant. Plants of this species grows 24” - 30” tall. Each tuber produces a single stem that terminates with a single “leaf” or inflorescence. Each leaf consists of an inverted umbrella of smaller leaflets that is 16” – 24” across. The stem is green with a few small dark charcoal to black-purple blotches. The plant alone is very ornamental. The inflorescence is produced from the naked tuber before the leaves are produced. The inflorescence is 12” – 15” tall. The inflorescence is single “flowered. The “flower” is actually a modified inflorescence that consists of the spathe (outer ornamental part) and the spadix (internal sexual bits). The spadix is 8” – 10” tall. The spadix appendage is slightly corrugate (wrinkled), dark purple-gray to dark red-purple tappers to a point. The spathe that surrounds the spadix is 4” – 8” long. The interior of the spathe is dark red-purple. The exterior is green at the base, blending to mustard green, and mustard-purple at the apex. Flowers last only a few days. The flowers attract flies for pollination. If pollinated the infructescence produces green berries that turn orange when ripe.
