Welcome to the parthenium weed portal. Parthenium hysterophorus is an annual herb that aggressively colonises disturbed sites. Native to southern United States, Mexico and Central and South America, it has been accidentally introduced into several countries and has become a serious agricultural and rangeland weed in parts of Australia, Asia, Africa and the Pacific Islands. It affects the production of crops and livestock, human and animal health, and biodiversity.
