Connecticut Plants
Spotted Joe-Pye-weed
Eutrochium maculatum (L.) E.E. Lamont

Connecticut has four species of Joe-Pye-weed, all with clusters of dull pink flowers. Spotted Joe-Pye weed got its name for having dark purple spots on its stems, though sometimes the stems are solid dark purple. Eastern Joe-Pye-weed also has purple-spotted stems, but the leaves are shorter and broader. Sweet Joe-Pye-weed (Eupatorium purpureum) has stems that are dark purple only at the leaf joints.
