Alocasia Macrorrhizos (Alocasia macrorrhizos) - Interesting facts
Plants in the genus Alocasia are closely related to plants in Colocasia. Both groups of plants are called Elephant's Ears due to their large leaves. Some species of Elephant's Ears have leaves large enough that they can be used as umberellas.Elephant's Ears are poisonous if ingested and contact with them may cause some mild irritation. The toxin in these plants is calcium oxalate. This compound can be washed away or neutralized from cooking. After the toxins are neutralized, the underground stem of some of the plants in Alocasia can be eaten. The edible plants of Alocasia are similar, but should not be confused with Taro: Colocasia esculenta.
