Arrowleaf Elephant's Ear
Xanthosoma sagittifolium
Medium · Some experienceAbout Arrowleaf Elephant's Ear
Arrowleaf Elephant Ear, also called Malanga or Tannia, is a large tropical aroid native to Central and South America and widely cultivated as a food crop throughout the tropics. It grows 4 to 6 feet tall with large, arrow-shaped leaves on long petioles emerging from a central corm. The starchy corms and cormels are an important carbohydrate source in the Caribbean, West Africa, and the Pacific Islands, valued for their nutty, earthy flavor when cooked. Unlike taro, Xanthosoma tolerates more shade and is often intercropped beneath tree canopies. The plant is the second most important tropical root crop in the aroid family after taro. Ornamentally, it creates bold tropical foliage effects and is increasingly used in temperate gardens as a seasonal specimen. It requires rich, moist soil and warm temperatures to produce well. All parts contain calcium oxalate crystals and must be thoroughly cooked before eating. The young leaves are also eaten as a cooked green vegetable in many tropical cultures.

History
Xanthosoma sagittifolium is native to northern South America and the Caribbean, where it was cultivated by pre-Columbian peoples for its edible starchy corms. Unlike the Old World taro (Colocasia esculenta, called "old cocoyam" in West Africa), Xanthosoma is a New World aroid — a distinct genus — sometimes called "new cocoyam" to mark the contrast. After Columbian contact, Xanthosoma was carried to West Africa (via the Atlantic slave trade era), where it substantially replaced Old World taro in many regions because it tolerates drier soils and has a more robust harvest profile; it is now a carbohydrate staple in Nigeria, Ghana, Cameroon, and neighboring countries, and has spread further to Southeast Asia and Pacific islands. In the Caribbean it is called "yautía" (Spanish) or "malanga" (Cuban Spanish) and is a staple ingredient of mofongo, callaloo, and many Afro-Caribbean dishes.
The large arrowhead-shaped leaves are used as wrapping in some West African and Caribbean cooking traditions; the young leaves are a leafy vegetable (called "kontomire" in Ghana, "callaloo" in parts of the Anglophone Caribbean) comparable to spinach. Like all Araceae, it contains calcium oxalate and must be cooked before consumption. Xanthosoma sagittifolium was domesticated by indigenous peoples of the Americas thousands of years before European contact.
It was carried to Africa during the slave trade era, where it became a vital food crop. Today it is grown across the tropics as a primary starch source, with major production in Nigeria, Ghana, and the Caribbean. The plant sustained many communities where other crops failed, earning it deep cultural importance in West African and Caribbean cuisine.
