Eupatorium serotinum

Eupatorium serotinum, also known as late boneset or late thoroughwort, is a fall-blooming herbaceous plant native to North America.[2] Like other members of the genus Eupatorium, it is about one to two meters tall and has inflorescences containing a large number of white flowers with disc florets and no ray florets.[3]

It ranges throughout most of the eastern United States, as far south as Mexico (near the Texas border),[4] as far north as the United States–Canadian border, and as far west as Nebraska and Texas.[2]

It grows in open sites (either dry or moist), and can hybridize with Eupatorium perfoliatum[2] and other members of the genus Eupatorium. Unlike wind-pollinated plants in this genus, E. serotinum is pollinated by insects.[5]
