Plants are (at this time 2021 - November) fully emerged, 2nd season seedlings, in 2” rose pots. With proper culture I expect plants to flower in 3-4 years. The plants offered here have solid green petioles. Photograph is of a selection of plants that are offered. Being a 2nd generation hybrid, based on the hardiness of the grandparents I think it’s safe to assume these are ONLY hardy in [USDA hardiness zone 9a -11], but cannot know for certain.
Both Amorphophallus impressus and Am. lewallei are native to eastern central Africa. 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. The leaf stem on these offered are solid light green. The plant alone is very ornamental. The inflorescence is produced from the naked corm before the leaves are produced. The inflorescence is 10” – 12” tall with a short pedicel and produced close to the soil level. 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 elongated and tapers to a blunt tip. I expect that is will be red-maroon colored. The spathe that surrounds the spadix is 5” - 8” long. I expect the outside of the spathe to be variously colored green with lighter green, whitish, or red-maroon irregular splotching. I expect the inside is to be variously colored cream-white, cream-green and dark red-purple. Flowers last a few days to a week.
