Erigeron salmonensis is a rare North American species of flowering plant in the family Asteraceae known by the common name Salmon River fleabane.[1] It has been found only in the Salmon River Canyon in central Idaho.[2]
Erigeron salmonensis grows on ledges and cracks in north-facing cliffs. It is a perennial herb that can reach up to 35 cm (14 inches) tall, forming a woody underground caudex. The inflorescence generally contains only 1 to 3 flower heads per stem. Each head contains 11 to 15 white ray florets surrounding many yellow disc florets.[1][3]
