DistributionSouthern Coastal Plain, Sandhills, and lowermost southeastern Piedmont.

Coastal Plain, southeastern VA to FL and eastern TX, north in the Mississippi Embayment to KY, AR, and OK.
AbundanceCommon to locally abundant in most of the southwestern half of the Coastal Plain (including the Sandhills), but rare to uncommon in the eastern counties, and rare in the edge of the Piedmont.
HabitatXeric to mesic, disturbed, Longleaf Pine savannas and flatwoods, sandhills, Loblolly Pine-oak-hickory woodlands, sandy fields, pastures, roadsides, powelines. Well adapted to disturbances, including fire. The species favors sandier soils than does the very similar Dog-fennel (E. capillifolium).
PhenologyFlowering and fruiting September-October.
IdentificationThis and E. capillifolium are our tallest eupatoriums (to 6.5 feet), with many strongly ascending branches bearing abundant tiny florets. Leaves of Yankeeweed are abundant and may be opposite or alternate, dissected into linear segments. Dog-fennel differs in its threadlike leaf segments less than 1 mm wide (vs. 1-2.5 mm wide in Yankeeweed). Both may occur near each other in the Coastal Plain, with Yankeeweed typically in the sandier places.
Taxonomic CommentsNone

Other Common Name(s)Coastal Plain Dog-fennel, Coastal Dog-fennel. Yankeeweed is a very odd and misleading name for a Southern species, but it is, by far, the most often used common name.
