Connecticut Plants
Eastern Joe-Pye-weed
Eutrochium dubium (Willd. ex Poir.) E.E. Lamont

Connecticut has four species of Joe-Pye-weed, all with clusters of dull pink flowers. Leaves of eastern Joe-Pye-weed narrow abruptly at the base, while the leaves of other species taper gradually. Other identifying marks for eastern Joe-Pye-weed are the fine purple spots on the stem, and the dome-shaped flower clusters (as opposed to the flat-topped clusters of spotted Joe-Pye weed).
