These plants are ¾” - 1” tubers. With proper culture I expect these will flower in 2 years. These were purchased in 2018 as small offsets (smaller than offered). I have not flowered them yet. One should flower in 2022 (knock on wood). The leaf photograph was lost when my previous phone died.
This species is native to the southern Sichuan province and northeast Yunnan province of China. This species as with most Amorphophallus and Arisaema species are seasonally dormant. Plants of this species grow 16” – 28”. 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 20” – 24” across. The leaf stem is green with black spots basally. The plant alone is very ornamental. The inflorescence is produced from the naked tuber before the leaves are produced. The inflorescence is 20” – 24” 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 5” – 7” tall. The spadix appendage (apical non-sexual part) is ¾” – 1 ¼” wide, cream-yellow, and sausage-shaped. The spathe that surrounds the spadix is 6” – 8” long. Internally the spathe is white to white-light green. The outside is light green. If pollinated, the Infructescence produces green berries that turn orange then red when mature. It is important to wear gloves if you harvest the berries as they juice can stain and irritate mammalian skin.
