Eastern purple coneflower is native to the central and eastern United States, centred on the Ozarks, the Mississippi Valley and the Ohio Valley, where it grows in dry open woods, prairies and barrens. VASCAN lists it as introduced in Quebec and in Ontario, so it is a garden escape here, not part of the original flora.
Linnaeus named it Rudbeckia purpurea in 1753, and Conrad Moench moved it to Echinacea in 1794. Echinacea comes from the Greek for spiny one, a reference to the spiny cone that looks like a sea urchin. It is a long-popular garden plant and several cultivars have earned awards from the Royal Horticultural Society.
