Erigeron filifolius is a North American species of flowering plants in the family Asteraceae known by the common names thread-leaf fleabane.[4]
Erigeron filifolius is widespread across much of western North America. It has been found in western Canada (British Columbia) and the western United States , primarily east of the crest of the Cascade Range of Washington (state) , Oregon, and northern California extending eastward to southern Idaho and northeast Nevada. Within its distribution, it occupies a large range of elevations from near sea level to 2,400 m (8,000 ft).[5][6][7][8]

Erigeron filifolius is a branched perennial herb up to 50 cm (20 in) in height. Leaves are long and thin, often thread-like, up to 8 cm (3 in) long. Each stem sometimes produces only 1 flower head per stem, sometimes flat-topped clusters of 10 or more. Each head may contain as many as 125 white, blue, pink, or lavender ray florets surrounding numerous yellow disc florets.[4][9][10][11]
