Erigeron utahensis is native to the western United States in Arizona, Utah, western Colorado, northwestern New Mexico, and southeastern California (Providence Mountains inside Mojave National Preserve in San Bernardino County).[2][3][4]

Erigeron utahensis is a perennial herb up to 60 cm (2 feet) tall, growing from a stout taproot and a branching underground caudex. Its branching stem and leaves are covered in whitish hairs. The inflorescence holds 1-5 flower heads, each 1-2 centimeters (0.4-0.8 inches) wide. They have yellow disc florets in the centers and 28–40 white, pink, lavender, or ray florets around the edges.[1]
