Erigeron robustior is a North American species of flowering plant in the daisy family known by the common name White cushion fleabane[2] or Willamette fleabane.[3] It is native to the southwestern Oregon and northern California in the western United States.[4][3]

Erigeron robustior grows in rocky of gravely slopes, sometimes in serpentine soil. It is an perennial herb up to 55 centimeters (22 inches) tall, forming a thin tap root, not growing into colonies as do some of the other species in the genus. The inflorescence usually contains 1-3 flower heads. Each head contains 21–36 white or pink ray florets surrounding many yellow disc florets.[2][5]
