These plants are near flowering size ¾” – 1¼” tubers in 3" rose pots or 4” plastic pots. With good culture, plants are expected to flower in 1 year. Plants are hardy in USDA zones 7b – 9b, but there are antidotal reports of plants surviving in 6b. I will eventually be trying these in my garden in zone 6b.
This species is native to Yunnan China, Vietnam (Dien Bien and Son La Provinces), and likely northern Laos (Phongsaly Province). These plants most likly originated from Chinese collections. This species as with most Amorphophallus and Arisaema species are seasonally dormant. Plants of this species grow 18” – 24”. Each tuber produces a single stem that terminates with a single “leaf”. Each leaf consists of an upward cupped umbrella of smaller leaflets that is 8” – 12” across. The stem leaf stem is green flushed pink. The plant alone is very ornamental. As with A. bulbifer, A. thaiensis, and others this species has an added bonus of producing new tubers at the “leaf” axils. These can be removed and planted the same as tubers produced from the soil. The inflorescence is produced from the naked corm before the leaves are produced. The inflorescence is 5” – 6” 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 2” - 3” tall and white or VERY light pink. The spadix appendage is white to cream and conical in shape. The spathe that surrounds the spadix is 4” – 5” long. The spathe is white to a very light pink with the basal inside dark purple. Flowers last only a few days. The flowers attract flies for pollination. I detect no fragrance or odor. If pollinated the infructescence produces green berries that lilac, then blue when ripe.
