| Distribution | Mountains and upper Piedmont.
Newf. to Ont. and MN, south to KY and IA; in Appalachians south to western NC. | |
| Abundance | Rare in the Piedmont; uncommon in the Mountains. This is a Watch List species. | |
| Habitat | Wet 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. | |
| Phenology | Flowering and fruiting late July-October. | |
| Identification | Spotted 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 Comments | Formerly treated as Eupatorium maculatum.
