Erigeron piperianus is a small perennial herb rarely more than 12 centimeters (4.8 inches) tall, producing a woody taproot. The plant produces many stems, but with only 1 flower head per stem. Each head has 25–40 yellow ray florets surrounding numerous yellow disc florets. The plant grows in dry, open, relatively flat land, often with sagebrush. It can be differentiated from the more widespread Erigeron linearis by its smaller size and the presence of sparse but prominent bristle-like hairs on the leaves, especially the lower part.[1]
