Eupatorium compositifolium commonly called Yankeeweed is a herbaceous perennial plant in Asteraceae native from North Carolina to Florida, west to Texas.[2] Like other members of the genus Eupatorium it has inflorescences containing a large number of white flowers with disc florets and no ray florets, and is 0.5 to 2 meters tall.[3]
It is closely related to Eupatorium capillifolium and Eupatorium leptophyllum and some authors consider all of them to be varieties of E. capillifolium.[4] However, E. compositifolium is not as tall as E. capillifolium and is found in dryer areas.[5]
Because it is not grazed by livestock, and mostly not eaten by wildlife, it is considered undesirable in places like pastures and controlled by means such as herbicides.[6]
