Eupatorium compositifolium, commonly called yankeeweed[3] and coastal dog fennel,[4][5] is a North American herbaceous perennial plant in the family Asteraceae native to the southern United States (from North Carolina to Florida and Texas ).[6] Like other members of the genus Eupatorium it has inflorescences containing a large number of small, white flower heads, each with 5 disc florets but no ray florets. The plant is 0.5 to 2 meters (20-80 inches) tall.[7] Flowers bloom August to October. Its habitats include sand dunes, disturbed areas, and flat-woods.[3]
It is closely related to Eupatorium capillifolium and Eupatorium leptophyllum and some authors consider all of them to be varieties of E. capillifolium.[8] However, E. compositifolium is not as tall as E. capillifolium and is found in drier areas.[9]
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.[10]
