Erigeron aureus (Alpine yellow fleabane) is a species of flowering plant in the daisy family, native to the Cascades and Rocky Mountains of northwestern North America (Alberta, British Columbia, Washington).
Erigeron aureus is a very small, short-lived herbaceous perennial growing to 10 cm (4 in), rarely 20 cm (8 in) tall. It has tufts of hairy grey-green leaves with large solitary yellow daisy-like flower heads to 2.5 cm (0.98 in) wide, appearing in summer.
The specific epithet aureus means "golden yellow".
In nature it inhabits ridges, crevices and rocky slopes, and is suitable for cultivation in a rockery, wall or similar sunny, well-drained site.
The cultivar 'Canary Bird', longer-lived than wild populations of the species, has gained the Royal Horticultural Society's Award of Garden Merit.
