Erigeron oreganus is a rare North American species of flowering plant in the family Asteraceae, called the gorge fleabane.[1] It has been found only in the Columbia River Gorge along the border between the US states of Washington and Oregon.[1][2]
Erigeron oreganus is a perennial herb up to 15 centimeters (6 inches) tall, with a large taproot.

The species grows in moist, shaded cliffs and ledges.[1]
