Erigeron flabellifolius

Erigeron flabellifolius is a rare North American species of flowering plants in the daisy family known by the common names fan-leaf fleabane .[1]

Erigeron flabellifolius is native to the mountains in the vicinity of Yellowstone National Park and Grand Teton National Park in Montana and Wyoming.[2] It grows at high elevations on cliffs, rockslides, and alpine meadows.[1]

Erigeron flabellifolius is a tiny perennial herb rarely more than 8 centimeters (3.2 inches) in height. Most of the leaves are clustered around the base of the stems. They are fan-shaped, narrowed at the base, triangular or 3-lobed at the far end. Each stem usually produces only 1 flower head per stem. Each head contains as many as 70 white, pink, or lavender ray florets surrounding numerous yellow disc florets.[1][3]
