Eriophyllum lanatum is a perennial herb growing from 30 to 60 centimeters (12 to 24 inches) in height, in well-branched clumps. Both the stems and leaves may be covered with a woolly gray hair, but some plants lack this. The leaves are 2.5–7.5 cm (1–3 in) long, linear on the upper stems, and slender and pinnately lobed on the lower stems. The hairs conserve water by reflecting heat and reducing air movement across the leaf's surface.
The flowers are yellow and composite, looking much like true sunflowers, and sometimes grow to about 5 cm (2 in) wide. Both the (8–12) ray and disk flowers are yellow, with one flower head on each flowering stalk. The flower heads have 6–14 rays, which are darker towards the base, and several disk flowers. They bloom from May to August. The seeds have scales at the tip.
