These plants are near flowering size, 3" - 4" tubers, in 5" - 6” plastic pots. With proper culture I expect these will flower in 1 year.
This species is native to tropical and subtropical regions of Nepal, Bhutan, northern India, Bangladesh, and Myanmar (Burma). 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” or an inflorescence. Each leaf consists of a large umbrella of smaller leaflets that is 24” – 30” across. The stem leaf stem is green spotted with pink. The plant alone is very ornamental. As with A. thaiensis, A. yulonensis, 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 tuber. In this species and many others, there is usually no growth until the following year. The inflorescence is 4” – 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 4” – 7” tall. The spadix appendage is white to cream colored. The spathe that surrounds the spadix is 6” – 10” long. The spathe is bright pink. Flowers last only a few days. The flowers attract flies for pollination. The “fragrance” is heavily reminiscent of old garbage. The Infructescence that can form is also very decorative. In late August – early October it consists of a corn cob like structure of green berries that turn yellow, then orange, then red when ripe. 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.
