Dusty Maidens may be up to 24 tall, with a branching inflorescence. The peduncle (flower stem) and involucre are quite hairy, but the hairs may be pressed against the stem. The hairs also thin out with age.

The leaves are bipinnately lobes, appearing quite intricately cut. The leaves, along with the rest of the plant, are quite hairy, although this thins out with age (apparently not just a human trait.)
