Erigeron trifidus is a Canadian species of flowering plant in the daisy family known by the common name Alberta fleabane.[1] It is native to the Provinces of Alberta and British Columbia in western Canada.[2]

Erigeron trifidus grows on talus and scree slopes in alpine zones at high elevations. It is a small perennial herb rarely more than 10 centimeters (4 inches) tall, producing a branching underground caudex. Leaves are usually 3-lobed, up to 3 cm (1.2 inches) long. The inflorescence is made up of only one flower heads per stem. Each head contains 20–40 white, lavender, or pink ray florets surrounding numerous yellow disc florets.[1]
