Colocasia gigantea

Giant elephant ear

A large corm-forming aroid from mainland Southeast Asia and western Malesia, 1.5–3 m tall, now often placed as Leucocasia gigantea. It grows in wet ground, often in the open, and is also grown as a vegetable, so it takes much more light and water than most aroids.
