[USDA zone 6a (?) - 10]
Plants are large, flowering size to near flowering size tubers. I expect these to flower in season. But being plants it is possible they will need another season to flower. The tuber photograph represents those offered here. The stolons have been removed from the second tuber.
This is a different offering than the other var. nanus listed. This plant was originally given to me, labeled Am. henryi, around 2010. After many mishaps it finally bloomed May 2022. It definitely is not Am. henryi. It is presently identified as Am. konjak var. nanus (Am. nanus). The leaf and petiole match the description; and the flower matches the second photograph in the article describing Am. nanus. It is however distinct from the Am. konjak var. nanus (Am. nanus) AGA - 2341-01 also offered.
Plants grow 12” – 20”. Each tuber produces a single stem that terminates with a single “leaf”. Each leaf consists of a large umbrella of smaller leaflets that is 12” - 18” across. The stem leaf stem is cream colored with irregular shaped olive green spots covering about ½ of the stems surface area. The plant alone is very ornamental. The inflorescence is produced from the naked tuber before the leaves are produced. The inflorescence is 14” - 16” 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 5” – 8” tall. The spadix appendage (apical non-sexual bit) is dark purple-maroon to purple-black and tapers to a blunt point. The spathe that surrounds the spadix is 4” – 7” long, with a rounded apex, rather than the elongated and flared on of typical Am. konjak. The outside of the spathe is dirty cream with some dark green spots. This shades to a dark purple-red apex. The inside is solid dark maroon-purple. Flowers last only a few days. The flowers attract flies for pollination. The “fragrance” is reminiscent of rotting meat or roadkill. I have yet to experience an infructescence.
