Rough mule's ears, scientifically known as Wyethia scabra or Scabrethia scabra, is a native plant with large, showy sunflower-like blossoms that appear in late summer and early fall. A long-lived, mounding perennial that dies back to a woody crown each winter and regrows each spring.

Mature plants can grow up to 20 inches tall and spread up to 3 feet wide. The plant's leaves and stems are covered in bristly hairs, giving them a rough, sandpaper-like texture.
