Ecological Role

Provides shade and microhabitat for small amphibians and insects. The roots (taro) are a significant food source for many cultures when properly cooked.

Easily Confused With

Alocasia and Xanthosoma species; Colocasia leaves usually point downward and have a matte finish, while Alocasia leaves often point upward and can be glossy.

Observation Tips

Look for these in damp garden borders or near ponds. Be careful when handling, as the sap contains calcium oxalate crystals which can irritate the skin.
