Some populations from further south (California, Colorado, etc.) were formerly considered as belonging to this species, but they have now either been moved to other taxa or recognized as distinct species.[http://www.tropicos.org/Name/2700723?tab=subordinatetaxa Tropicos, Erigeron peregrinus (Banks ex Pursh) Greene ]

Erigeron peregrinus is a perennial herb up to 70 centimeters (28 inches) in height, spreading by means of underground rhizomes. It has hairless to hairy leaves reaching up to 10 centimeters long at the base of the branching stem, getting smaller higher up on the stem. The plant usually produces only one flower head per stem, each with 30–80 blue, purple, pink, or white ray florets surrounding numerous disc florets. Flowers bloom July to August. Its habitats include stream banks, bogs, and moist mountain meadows.{{Cite web |title=Lady Bird Johnson Wildflower Center - The University of Texas at Austin |url=https://www.wildflower.org/plants/result.php?id_plant=ERPE3 |access-date=2022-03-13 |website=www.wildflower.org}}
