Rudbeckia fulgida (Orange Coneflower, Eastern Coneflower) also has a resemblance. This latter species has a limited distribution in Wisconsin. It has flowers about 1.5 to 2.5 inches wide, 10 to 15 ray florets, and stems that are sparsely hairy. Ethnobotany: The Potawatomi prepared a tea from the roots and used it to treat colds. They also used the disc florets to prepare a yellow dye (Smith, pp. 48-49, 120, 1933).
