General Description
This perennial species has clustered stems 20-50 cm tall, from a loosely branched rootcrown. The lance-shaped basal leaves have petioles and are up to 15 cm long and 2 cm wide. The stem leaves are alternate, smaller and narrower, and the uppermost do not have petioles. The whole plant is densely whitehairy. The flowering heads are borne in a compact, rounded inflorescence. The individual heads are 5-8 mm high with involucral bracts that are hairy toward the greenish base. The upper portion of the bracts is dark brown or greenish-black.

Diagnostic Characteristics
Easily confused with A. lanata and A. anaphaloides. Antennaria lanata and A. anaphaloides almost always grow in well drained soil, whereas A. pulcherrima grows in wet meadows and other more-or-less constantly moist sites. Antennaria lanata is smaller in all parts and has only one prominent leaf vein. Antennaria anaphaloides tends to be smaller than A. pulcherrima and it has paler phyllaries.
