General Information

Bidens pilosa is an annual plant producing an erect, much-branched stem up to 100cm tall, though the plant can often flower, seed and then die when much smaller.
The plant is gathered from the wild for local use as a food and medicine. In parts of Africa, the plant is allowed to remain as a weed in cultivated ground, and it is also sometimes cultivated[

]. Bidens pilosa is a problematic species for many reasons throughout its range. A troublesome weed to at least 30 crops in over 40 countries, it is known to significantly reduce crop yields by almost 50% in some cases. It forms dense stands that can out compete, out grow, and eliminate crop and native vegetation, specifically the lower vegetative strata, over large areas. It prevents the regeneration of these plants as well, given its allelopathic properties. Leaf and root extracts are known to significantly suppress germination and seedling growth of many plants and are believed to remain active throughout decomposition. Furthermore, it grows three times faster than similar plant species. All of these properties render it a quite formidable competitor[

Its burrs are a nuisance to people and wild life. The burrs are also a troublesome seed contaminant as they are difficult to separate from grain.
