Colocasia gigantea

Colocasia gigantea, also called giant elephant ear or Indian taro, is a 1.5–3 m tall herb with a large, fibrous, inedible corm, producing at its apex a whorl of large leaves. The leaf stalk is used as a vegetable in some areas in South East Asia and Japan. Known as dọc mùng in Vietnam (bạc hà in some provinces in southern Vietnam), it is often used in canh chua and bún. Colocasia gigantea is close to Alocasia macrorrhizos and is thought to be produced from natural crossing between A. macrorrhizos and C. esculenta.
