Amorphophallus atroviridis

[USDA zone 9a – 11a]


These plants are of legally obtained (proper permits etc.) wild stock. These were obtained prior to the Covid pandemic and I have slowly grown these precious babies to maturity. My hope is to introduce new blood into the US via offsets and eventually seedlings. In time I hope to list plants as individual cultivars as some are VERY spotted and one seems to have a hint of variegation. 

Inflorescense photos are of '#4', the rest are various other cultivars from this import group.


This species is native to central Thailand. This species as with most Amorphophallus and Arisaema species are seasonally dormant. Plants of this species grow 8” – 16”. Each tuber produces a single stem that terminates with a single “leaf” OR an inflorescence. Each leaf consists of a large umbrella of smaller leaflets that is 5” –8” across. The leaf stem is rust-red to red-brown, variously covered with irregular white to silver lichen-like spots. The plant alone is very ornamental. The inflorescence is produced from the naked tuber before the leaves are produced. The inflorescence is 8” – 12” tall, 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 (apical non-sexual part) is slightly thinner, cream to light pink, and tapers to a sharp point. The spathe that surrounds the spadix is 5”– 6” long. Internally the spathe is white, white flushed pink, to light pink. The outside is light pink to white veined pink. If pollinated, the Infructescence produces green berries that turn orange-red (?) when mature. It is important to wear gloves if you harvest the berries as they juice can stain and irritate mammalian skin.


It is usual for this plant to NOT produce a growth the same season after it flowers. It skips that season and grows the next year. Tubers often flower every other to every third year.
