An Australia, Colocasia esculenta var. aquatilis is native to the Kimberley region of Western Australia; variety esculenta is naturalised in Western Australia, the Northern Territory, Queensland and New South Wales.
Its primary use, however, is the consumption of its edible corm and leaves. In its raw form the plant is toxic due to the presence of calcium oxalate, although the toxin is destroyed by cooking and the presence of needle-shaped raphides in the plant cells. However it can be rendered palatable by cooking, or by steeping in cold water overnight.
It is also sold an ornamental aquatic plant.
