Amorphophallus paeoniifolius is cultivated for its edible tubers.

Tubers from Amorphophallus paeoniifolius are used as food in many parts of the Old World tropics. The plant flowers annually with a large, foul-smelling, purple-red bloom. The scent attracts insects who mistake it for meat while pollinating the aroid.

A. paeoniifolius looks like a tree with a trunk and branches, but the entire plant is a single leaf. Amorphophallus has a camouflaged 'stem' to protect its large leaf as it is not actually a stem but a petiole. If the petiole is damaged by a hungry herbivore, the entire plant is jeopardized.

Botanical description

Amorphophallus paeoniifolius, which belongs to the arum family and originates from tropical and subtropical Asia to northern Australia.

Growth habit

The elephant foot yam grows from its tuber, which each year sends up a single large leaf or a flower. Under the right conditions, this elephant foot yam can become a true giant. The leaf can reach up to two meters in height and becomes an exotic ornamental tree. When Amorphophallus paeoniifolius is not flowering, it is this enormous leaf that takes over and gives the elephant foot yam its unique appearance.

Care

Plant Amorphophallus paeoniifolius in well-draining soil with perlite and bark, such as our aroid soil. Elephant foot yam thrives best in indirect light and loves warmth. Let the soil dry out between waterings, and normal room temperature works excellently, just avoid drafts!

To propagate elephant foot yam, tubers are primarily used. During the elephant foot yam's dormant period, you can carefully separate daughter tubers that form around the main tuber. These tubers are planted in well-draining soil and watered sparingly until growth begins. Amorphophallus paeoniifolius grows slowly.

Flowering

On the first day of flowering, the female flowers are receptive to pollen, and the strong odor attracts insects that are trapped inside the flower overnight. This allows pollen on the insects to be transferred to the female flowers.

On the second day, the female flowers are no longer receptive, and the male flowers begin to produce pollen. The flower opens again, allowing the insects to carry pollen to other flowers. This prevents self-pollination and inbreeding.

The female flowers develop into red berries, while the rest of the flower withers. The berries, which are bright red when ripe, are somewhat oval in shape. During flowering, the flower also emits heat to mimic a fresh carcass. Yikes!
