DistributionMountains only, low to mid elevations. The literature records on the map come from the BONAP database and thus may be open to question.

Western VA to eastern KY, south to western NC and eastern TN.
AbundanceNot well known in NC, as it was described only in 1990, and most botanists, and certainly most field biologists, are not familiar with it. The Digital Atlas of the Virginia Flora website calls it "frequent" in the southwestern mountains there. Weakley's (2018) maps shows it as "uncommon" in the NC mountains. Thus, the website editors suggest that it is uncommon to perhaps frequent in the mountains; the NCNHP's State Rank of S3 seems to be essentially correct, though more information is greatly needed.
HabitatMesic soils of northern hardwood forests, cove hardwoods.

PhenologyFlowering and fruiting July-October.
IdentificationAppalachian Joe-pye-weed has a dome-shaped inflorescence and only 4-7 florets per head; thus it distinct from E. maculatum. From E. purpureum, it differs by having copious gland-tipped hairs throughout the stem (vs. glabrous below the inflorescence), and having gland-tipped hairs on leaf undersides (vs. no gland-tipped hairs but may have sessile resin glands). The quite common E. fistulosum has hollow stems and long leaves mostly in whorls of 5 or more, whereas this species has solid stems and just 3-4 broader leaves in a whorl.
Taxonomic CommentsThis species was newly named in 1990 by Eric Lamont. As this is not a rare species, previous specimens were likely labelled as E. purpureum, if not other species as well.
