Easily Confused With
Alocasia and Xanthosoma species; Alocasia leaves typically point upward, while Colocasia (Elephant Ear) leaves usually point downward.
Observation Tips
Be cautious as the plant contains calcium oxalate crystals which are toxic if ingested and can cause skin irritation; wear gloves when handling.
Interesting Facts
The leaves have a 'lotus effect' where water beads up and rolls off, carrying away dust and keeping the leaf clean. Despite being toxic raw, the roots are edible when properly cooked and are known as Taro.
