Amorphophallus konjac (live bulb)

Amorphophallus konjac BULB. (Araceae) Voodoo lily. It produces a single leaf from a subterranean tuber. The tuber shrinks away as the new leaf grows and during the growing season a new, larger tuber replaces it. The fleshy leaf stalk (petiole) is a very interesting mottled pinkish-gray and olive green. The single intricate leaf consists of a horizontal blade on the vertical petiole which is divided into three sections, giving an umbrella-like effect. The starchy tubers are edible and this plant is grown for food in some parts of the world, processed into a tasteless flour or stiff jelly (which can be used as a vegan substitute for gelatin).
