''Eupatorium compositifolium'' commonly called Yankeeweed is a North American herbaceous perennial plant in sunflower family native to the southern United States (from North Carolina to Florida and Texas).〔(【引用サイトリンク】 work = Flora of North America )〕〔(Biota of North America Program 2014 county distribution map )〕 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 metres (20-80 inches) tall.〔(【引用サイトリンク】 Eupatorium )〕 It is closely related to ''Eupatorium capillifolium'' and ''Eupatorium leptophyllum'' and some authors consider all of them to be varieties of ''E. capillifolium''. However, ''E. compositifolium'' is not as tall as ''E. capillifolium'' and is found in dryer areas. 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. ==References==
