Parthenium hysterophorus, commonly known as "carrot grass," is an invasive weed species native to the Americas but now widely distributed in many parts of the world. It is often referred to as "carrot weed" or "Congress grass" as well. This plant is known for its ability to rapidly colonize disturbed habitats, including agricultural fields, roadsides, waste areas, and pastures.
