Erigeron glacialis
Erigeron glacialis, the glacial daisy, glacial fleabane, Subalpine fleabane,[2] or wandering fleabane,[3] is a western North American perennial plant in the family Asteraceae.[4] Erigeron glacialis is native to the mountains of western North America, including Cascades, the Sierra Nevada, and the Rocky Mountains.[5] It has been found from Alaska and Yukon south as far as California, Arizona, and New Mexico.[6] In the Sierra Nevada, it may be found with mixed coniferous and upper montane vegetation types, and in the alpine zone to 11,200 feet (3,400 m).[4][3] Erigeron glacialis is a perennial herb up to 70 cm (28 inches) tall, with a thick taproot and spreading by means of underground rhizomes. Leaves are up to 20 cm (8 inches) long, linear-oblanceolate to broadly lanceolate or spatulate. Each stem sometimes produces only 1 flower head, sometimes a group of up to 8. Each head has up to 80 white, blue, pink, or lavender ray florets surrounding numerous yellow disc florets.[2] It blooms between July and September.[4]
