DistributionMountains and upper Piedmont.

Newf. to Ont. and MN, south to KY and IA; in Appalachians south to western NC.
AbundanceRare in the Piedmont; uncommon in the Mountains. This is a Watch List species.
HabitatWet to moist meadows, marshes, fens, seepages, damp areas in grassy balds, and even in cove forests (Weakley 2018). It favors high pH soil, perhaps explaining it scarcity.
PhenologyFlowering and fruiting late July-October.
IdentificationSpotted Joe-pye-weed may indeed have red-purple specked stems, but not always distinctly so. Note that Coastal Plain Joe-pye-weed (E. dubium) can also have spotted stems, but is otherwise very different, and the ranges are quite separate. Its inflorescence is generally flat-topped to gently rounded, unlike our other species (which are strongly rounded or globe-shaped), and has 9-22 florets per head, many more than our other species.
Taxonomic CommentsFormerly treated as Eupatorium maculatum.
