Overview
Colocasia as a genus is one of three similar genera that originate from Malaysia. Its members can be deciduous or evergreen, tuberous-rooted perennials. It is often found growing along river banks and has a dormant period during the dry season in places like South Africa. Colocasia species have large, round or arrow-shaped leaves, often with conspicuous veins. Insignificant flowering spathes are rarely in cultivation. Colocasias can be used effectively as marginal plantings in ponds and lakes. They grow best out of full sunlight and thrive in wet soil. All parts poisonous if eaten uncooked, and leaves may irritate skin.
