Erigeron poliospermus is a species of flowering plant in the daisy family known by the common names gray-seeded fleabane and purple cushion fleabane. Native to western North America, it is mainly found in east of the Cascade Range in Washington, Oregon, and Idaho. A species of desert, scrub and rocky habitats below 1,800 metres (6,000 ft), it occasionally found at higher elevations.
Erigeron poliospermus is a small perennial herb rarely more than 15 cm (5.9 in) tall, producing a woody taproot. The plant generally produces only 1-3 flower heads per stem. Each head has 15–45 pink, purple, or white ray florets surrounding numerous yellow disc florets. The ray florets are lacking in var. disciformis. The involucre bracts, 5–9 mm (0.2–0.4 in) long, are more or less the same length and are sparsely to densely white-hairy.
