Alocasia and Colocasia belong to the plant family known as Araceae. But they have major differences.
Alocasia and Colocasia more than belong to the same plant family. Gardeners refer to them by a nickname "elephant ears." This is in tribute to the large, flappy heart shapes of their leaves.
Alocasia plants hold their leaves horizontally, with the tips sort of pointed upward. Also, Alocasias tend to prefer some shade and well-drained soil.
By contrast, Colocasia plants hold their leaves downward. Moreover, Colocasia prefer full sunlight and lots of water.
Another member of the Araceae family, Xanthosoma is similar to Colocasia in how it holds its leaves and how soft they are compared with Alocasia. But Xanthosoma leaves are more arrow-shaped than heart-shaped.
Edible or Not?
Some leaves from these plants are edible, while some are not. The best way to find out--or rather, to avoid the nonedible ones--is to stick to the leaves sold at your local grocery store.
