Like most species in this genus, antennaria parvifolia
spreads via stolons, creating low mats of many closely-spaced, reddish-green stems, which can reach a height of 6 inches, though 4 inches is more common. The stems have a light covering of soft, non-glandular hairs. Leaves are also hairy, on both sides, and, for basal leaves, their length is typically more than twice the width. The alternate stem leaves are a little shorter, and linear in shape.
The inflorescence usually contains between two and seven flowerheads, which either have only pistils, or only stamens; the former is more common. Phyllaries are light in shade but variable in color - brown, pink, green, or nearly white. Flowerheads are somewhat larger than those of similar pussytoes species; the involucre is around 0.4 inches long, while the (pistillate) corolla is around 0.3 inches.
