Range and Habitat

edit

Erigeron aureus is native to the Cascades and Rocky Mountains of northwestern North America (Alberta, British Columbia, Washington).[6] It grows in high mountains on exposed ridges and rocky slopes and in rock crevices.[3][7]

Description

edit

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.[8][7][9][10]

Cultivation

edit

Erigeron aureus is suitable for cultivation in a rockery, wall or similar sunny, well-drained site.

In the UK it thrives in the warmer western and southern coastal areas, though it is listed as hardy down to −10 °C (14 °F).[11] The cultivar 'Canary Bird', longer-lived than wild populations of the species, has gained the Royal Horticultural Society's Award of Garden Merit.[11][12]
