Bush’s Coneflower and Gray-Headed Coneflower, though both members of the asterae (daisy) family of flowers, belong to separate sub-groups (genera). Bush’s Coneflower, Echinacea paradoxa, is the only yellow member of its clan and it readily cross-pollinates with its pink cousins, contributing much to recent echinacea introductions. Gray-Headed Coneflower, Ratibida pinnata, is a tall yellow-petaled prairie native related to the more familiar Mexican Hat plant.
Members of the Rudbeckia family, more commonly called Black or Brown-Eyed Susans, are also referred to as coneflowers. For more information; CLICK HERE
