Plants are are 1½” – 2” long, dormant stolons of the hybrid Amorphophallus 'Mary Sizemore'.  With proper care I expect plants to flower in 2 - 3 years.

This plant is a rare registered Amorphophallus hybrid. The parentage is (albus x konjak ‘Nightstick’). Plants of this species grows 24” – 36” tall. Each tuber produces a single stem that terminates with a single “leaf”. Each leaf consists of an umbrella of 5 – 7 smaller leaflets that is 24” – 30” across. The petiole is green with scattered black spots. The inflorescence is produced from the naked tuber before the leaves are produced. The inflorescence is 24” – 30” 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 20” – 30” tall. The spadix appendage (apical non-sexual bit) is dark purple-maroon and tapers to a blunt point. The spathe that surrounds the spadix is 12” – 20” long. The outside of the spathe is bright green. The inside is red-maroon. Flowers last only a few days. The flowers attract flies for pollination. Flowers last only a few days.
