Erigeron concinnus explained

Erigeron concinnus, the Navajo fleabane, tidy fleabane or hairy daisy, is a perennial flowering plant in the family Asteraceae.^[1]

Erigeron concinnus is native to the dry mountains of the Mojave Desert around Death Valley in southeast California, north and east to Nevada, Idaho, Utah, Wyoming, Montana, Colorado, Arizona, and New Mexico;^[2] in the California portion of its range, it grows at elevations of 1200–1800 m. Some of the known populations lie inside Mojave National Preserve.^[3]

Erigeron concinnus grows in sandy to rocky soils, and can reach a height of 6-. The leaves are 2- long, lanceolate to linear, broadest near the rounded apex. The flower heads are sometimes produced one per branch, sometimes in groups of up to 6, each head 7- in diameter, with 50-125 white, pink, or blue ray florets and yellow disk florets.^{[4] [5]}
