Erigeron rydbergii is a North American species of flowering plant in the family Asteraceae known by the common name Rydberg's fleabane.[1] It is native to the western United States, in the Rocky Mountains and other nearby ranges in the states of Montana, Wyoming, Idaho, and Utah.[2]
Erigeron rydbergii grows in subalpine to alpine slopes at high elevations. It is a tiny perennial rarely more than 6 centimeters (2.4 inches) tall, forming a thick taproot. The inflorescence generally contains only 1 flower head per stem. Each head contains 15–35 blue, purple, or rarely white ray florets surrounding many yellow disc florets.[1]
