Tithonia diversifolia or Mexican sunflower of the Asteraceae family

A species of flowering plant in the Asteraceae family known as Tithonia diversifolia is often referred to as the tree marigold, Mexican tournesol, Japanese sunflower, or Nitobe chrysanthemum. Despite being an imported plant, it is native to Mexico and Central America but has a practically pantropical distribution.  

They could be either annual or perennial, depending on the region. It has demonstrated excellent potential for increasing soil fertility in nutrient-poor soils. It originated in Mexico, and studies have indicated that it may help poor African farmers.  

This weedy plant has emerged as a viable substitute for pricey synthetic fertilizers because of its rapid growth. It has been demonstrated to boost plant yields and soil nitrogen (N), phosphorus (P), and potassium (P) nutrients (K).
