Tithonia (Tithonia diversifolia), also known as Mexican sunflower or tree marigold, is a perennial shrub that is native to Mexico and Central America. Often introduced for its attractive flowers, it is now found in humid and sub-humid parts of Africa, Asia, and South America. It grows on most soils, can reach 3 meters (m) in height, and is moderately resistant to drought  (Heuzé et al. 2016; Orwa et al. 2009).
