Different Antennaria species reach between 10 cm and 50 cm in height. The leaves are basal and often stem leaves. The name Antennaria refers to the projecting stamens seen on the male flowers of some species, resembling insect antennae.{{eFloras|1|101977|Antennaria |first=Randall J. |last=Bayer |volume=19, 20 and 21}} {{Cite book|last=Coombes|first=Allen J.|url=https://www.worldcat.org/oclc/741564356|title=The A to Z of plant names : a quick reference guide to 4000 garden plants|date=2012|publisher=Timber Press|isbn=978-1-60469-196-2|edition=1st|location=Portland, Or.|pages=46|oclc=741564356}}

Antennaria species are used as food plants by the larvae of some Lepidoptera species including Vanessa virginiensis (American painted lady),{{Illinois Wildflowers|savanna/plants/pl_pussytoes|Plantain-Leaved Pussytoes (Antennaria plantaginifolia)}} Coleophora pappiferella (which feeds exclusively on A. dioica), Schinia verna (which feeds on several Antennaria species).{{Citation needed|date=October 2021}}
