Eupatorium leptophyllum, commonly called false fennel,[3] is a herbaceous perennial plant in the family Asteraceae native to the southeastern United States from Mississippi to the Carolinas.[4][5] Like other members of the genus Eupatorium, it is about one to two meters (40-80 inches) tall and has inflorescences containing a large number of tiny white flower heads, each with 5 disc florets but no ray florets.[6] E. leptophyllum grows in wet areas and can grow in shallow water, often at the edges of ponds.[4]
