Amorphophallus maximus

[USDA zone 10 ->]


These plants are small ½” – ¾”, dormant tuber of the hybrid Amorphophallus maximus ‘Strain #1’. With proper culture I expect these to flower in 3-4 years.

This species is native to Somalia, Kenya, Tanzania, and Zimbabwe in tropical eastern Africa. There are two subspecies; A. maximus ssp. fischeri and A. maximus ssp. maximus. I am uncertain which subspecies this represents. This species as with most Amorphophallus and Arisaema species are seasonally dormant. Plants of this species grows 24” – 36” 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” – 30” across. The stem is green, with large chocolate brown blotches, and covered in short soft trichomes. The inflorescence is produced from the naked tuber before the leaves are produced. The inflorescence is 8” – 40” tall, but averages 10” – 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 8” – 20” (+) tall, The spadix appendage is dark red-purple to smoky purple, extremely elongated, and tapering to a point. The spathe that surrounds the spadix is 7” – 9” long. The spathe is cupped around the base of the spadix but flares open apically. The spathe is dark purple-red to purple-black internally. The exterior is dark purple black but covered with a greyish bloom. Flowers last only a few days.
