What distinguishes Echinacea from Coneflower?
One of the three distinct genera referred to as coneflowers are Echinacea. Echinacea Angustifolia and Echinacea purpurea are two well-known members of the Echinacea genus. Purple coneflowers, or (more ambiguously) plain coneflowers, is the popular name for members of the Echinacea species.
