Coastal Plain Joe-Pye Weed

Eutrochium dubium

Also known as Coastal Joe-Pye Weed, Three-Nerved Joe-Pye Weed

Coastal plain Joe-Pye weed towers above damp fields and bog margins with sturdy purplish stems and whorled, triple-nerved leaves. In late summer, massive dome-shaped clusters of tiny mauve florets open, drawing clouds of swallowtails, monarchs, and native bees. This moisture-loving perennial thrives along Atlantic shores, anchoring coastal wetlands and providing vital late-season nectar.
