About Eupatorium linearifolium Walter
Eupatorium linearifolium, commonly called narrowleaf bushy eupatorium, is a herbaceous plant native to North America that blooms in the fall. Like other species in the genus Eupatorium, it produces inflorescences that hold many small white flower heads. Each flower head contains 5 disc florets and has no ray florets. Authoritative works including the Flora of North America classify all plants that were previously treated as Eupatorium cuneifolium within Eupatorium linearifolium. Compared to other Eupatorium species, the most distinctive characteristic of Eupatorium linearifolium is that its stems branch near the ground. Eupatorium linearifolium occurs in the southeastern and south-central United States, and can be found across all coastal states stretching from Texas to Virginia, though it is likely extirpated in Virginia.
