[USDA zone 11 – 13]
 
Plants are second year seedlings. Most are beginning their second growth (December 2022). Plants are 5" - 7" tall in 4” plastic pots.  With proper culture I expect these will flower in 2 - 3 years. 
 
This species is native to Borneo (eastern Kalimantan, Indonesia and Sabah and Sarawak Malaysia). This species as with most Amorphophallus and Arisaema species are seasonally dormant. Plants of this species grows 24” – 36”tall. Each tuber produces a single stem that terminates with a single “leaf”. Each leaf consists of a large umbrella of smaller leaflets that is 18” – 24” across. The stem leaf stem is green marbled with irregular lighter green and cream-white blotches. The plant alone is very ornamental. The inflorescence is produced from the naked tuber before the leaves are produced. The inflorescence is 18” – 24” 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 12” – 16” tall. The spadix appendage is tan-purple to dark red-purple and slightly tapers to blunt point. The spathe that surrounds the spadix is 4” – 8” tall. The base is closely cupped around the base of the spadix with the apex splayed out away from the spadix. The outside of the spathe is bright green to olive green with some irregular purple flushing. The inside is light tan-pink to dark maroon-purple. Flowers last only a few days. If pollinated, the Infructescence produces green berries that turn yellow, then orange when mature. It is important to wear gloves if you harvest the berries as they juice can stain and irritate mammalian skin.
