Erigeron subtrinervis, called the three-nerved daisy,[3] the three-nerve fleabane,[4] or the hairy showy daisy,[4] is a North American species of flowering plants in the family Asteraceae. It grows in various mountains of western Canada and the western United States: Rocky Mountains, northern Cascades, Black Hills, etc., from British Columbia and Washington (state) east to North Dakota and south as far as New Mexico.[5][3]
Erigeron subtrinervis grows in openings and along roadsides in aspen groves and conifer forests, as well as on ridges and mountain peaks at high elevations. It is a perennial herb up to 90 cm (3 feet) tall, producing underground rhizomes and a woody caudex. The inflorescence generally contains 1-21 flower heads per stem, in a flat-topped array. Each head contains 100–150 purple or lavender ray florets surrounding many yellow disc florets.[6]
