"Eupatorium serotinum", also known as late boneset or late thoroughwort, is a fall-blooming herbaceous plant native to North America.cite web | url = http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=242416536 | title = Eupatorium serotinum | work = Flora of North America ] 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. [cite web | url = http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=112351 | title = Eupatorium | work = Flora of North America ]

It ranges throughout most of the eastern United States, as far south as Mexico (near the Texas border) [cite journal | author = Schmidt, Gregory J. & Schilling, Edward E. | year = 2000 | title = Phylogeny and biogeography of "Eupatorium" (Asteraceae: Eupatorieae) based on nuclear ITS sequence data | journal = American Journal of Botany | volume = 87 | issue = 5 | pages = 716–726 | pmid = 10811796 | url = http://www.amjbot.org/cgi/content/full/87/5/716 | doi = 10.2307/2656858 ] , as far north as the United States–Canadian border, and as far west as Nebraska and Texas.

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