Plants are around 2" tubers.  With proper culture I expect these will flower in 2 years. I expect my stock plant to flower in 2023 and will update with a photograph. Photograph of the tubers is representative of this offering.

This is an intra-sectional hybrid between the closely related Am. dunnii and Am. yunnanensis. Am. dunnii is native to southeastern China. A. yunnanensis is native to southeastern China, northern Laos, and northern Vietnam. The hybrid definitely shows hybrid vigor and the Am. dunnii propensity to produce offsets. This hybrid as with most Amorphophallus and Arisaema species are seasonally dormant. Plants sprout from a subterranean tuber in the same fashion as the spring Crocus. I expect plants of this species grow 24” – 30” tall. Each tuber produces a single stem that terminates with a single “leaf” OR inflorescence. Each leaf consists of a large umbrella of smaller leaflets that is 20” – 24” across. Leaves if grown under bright light will have a pink to reddish edge. The petiole (leaf stem) on these offered are solid light greens. The plant alone is very ornamental. The inflorescence is produced from the naked corm before the leaves are produced. The inflorescence is 15” – 20” 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” - 6” tall. The spadix appendage is bulbous, oblong and barely tapers to a blunt tip. The spadix appendage is cream to light yellow-green. The spathe that surrounds the spadix is 5” - 8” long. The exterior of the spathe is medium green with light cream-pink to white irregularly shaped spots. The interior is light green to light yellow-green. The interior basal ¾” – 1½” is dark red-purple. Flowers last a few days to a week. Fragrance is undetectable or slightly of carrots (?). So not a dumpster fire or dead walrus.
