Erigeron salmonensis is a rare North American species of flowering plant in the daisy family 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 up to 35 cm (14 inches) tall, forming a woody underground caudex.
