Colocasia esculenta is a tropical plant grown primarily for its edible corms. The root vegetable is most commonly known as taro. It is the most widely cultivated species of several plants in the Araceae family, which are used as vegetables for their corms, leaves, and petioles. Taro corms are a food staple in African, Oceanic and South Asian cultures, and taro is believed to have been one of the earliest cultivated plants.
