Tayer

Xanthosoma sagittifolium is a tropical flowering plant from the family Araceae. It produces an edible, starchy corm. X. sagittifolium is native to tropical America where it has been first cultivated. Around the 19th century, the plant spread to Southeast Asia and Africa and has been cultivated there ever since. X. sagittifolium is often confused with the related plant Colocasia esculenta (Taro), which looks very similar and is also used in a similar way. Both plants are often collectively named Cocoyam. Depending on the region, there are various common names for X. sagittifolium, including Tannia, Yautia, Malanga, (New) Cocoyam, the Arrowleaf Elephant's Ear, or American Taro. Cultivars with purple stems or leaves are also variously called Blue Taro, Purplestem Taro, Purplestem Tannia, and Purple Elephant's Ear among others.
