These plants are divisions / offshoots of A. thaiensis RSS 0019-02. The plants offered here are 2½”- 3½” offsets in 5" - 6” pots. With proper care, plants should flower in 1 year.
This species flowers in late summer (mid-late September in USDA zone 6a). After flowering, it produces it's growth just as the "flower" matures and opens.
This species is native to mountainous areas of northern Thailand. This species as with most Amorphophallus and Arisaema species are seasonally dormant. Plants sprout from a subterranean tuber in the same fashion as the spring Crocus. Plants of this species grow 15” – 20” 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 15” – 20” across. As with A. bulbifer, 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 leaf stem is brown to brown-rust with sparse irregular grey-white markings. These markings resemble lichens. The plant alone is very ornamental. The inflorescence is produced from the naked corm before the leaves are produced. The inflorescence is 10” – 15” 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 3” – 5” tall and enclosed within the spathe. The spadix appendage (apical non-sexual part) is bulbous, 1” – 1½”wide, and cream-white. The spathe that surrounds the spadix is 3½” – 6½” long. The spathe interior is medium green. The exterior is darker green blotched light green to silvery white. Flowers have a fragrance akin to a combination of new carpet and Naphthalene (mothballs). Flowers last a few days to a week. 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 lilac then dark blue when ripe. It is important to wear gloves if you harvest the berries as they juice can stain and irritate mammalian skin.
