Xanthosoma sagittifolium
Tannia, also called yautía, malanga or new cocoyam, is a large arrow-leaved aroid grown across the tropics for its edible starchy corms and cormels. It thrives in warm, humid conditions with rain spread through the year and is notably shade-tolerant, but its wild origins are uncertain because it has been cultivated so long.
Where it grows wild
A robust terrestrial herb from a thick corm, found in forest clearings, edges, stream banks and disturbed ground, and very widely in gardens and farm plots. It is grown both in full sun and under crops such as bananas and cocoa.
Records run from sea level to about 2575 m with a median of 865 m; the highest records are probably cultivated or escaped plants.
