Erigeron canaani is a rare species of flowering plant in the family Asteraceae known by the common name Abajo fleabane.[2] It has been found only in southern Utah, in sandy soil and in cracks on cliff faces in Washington, Kane, and San Juan Counties.[3]

Erigeron canaani is a perennial herb up to 30 cm (12 inches) tall, producing a taproot. One plant can produce several flower heads, sometimes one per branch, sometimes in groups of 2 or 3. Each head has 15–22 white or purpleray florets, plus numerous small yellow disc florets.[2]

The species is named for Canaan Mountain south of Zion National Park. The common name "Abajo fleabane" refers to the Abajo Mountains south of Canyonlands National Park.[4]
