Eupatorium altissimum (tall thoroughwort) is a perennial plant whose native range includes much of the eastern United States and Canada. It almost always grows on limestone soils, as does Brickellia eupatorioides, which it is potentially confused with. It can hybridize with Eupatorium serotinum.[2]

It is part of Eupatorium even when that genus is defined narrowly, to include about 40 species of mostly white-flowered plants of North America, Asia, and Europe.[3][4]
