Native to North America?

Yes

Sometimes confused with

Antennaria neglecta:
plants combining the following 2 features: upper stem leaves terminated by a flat or curling, weak-textured appendage and new rosette leaves gray-green with woolly hairs on the upper surface (vs. A. howellii, which are plants with either the upper stem leaves merely pointed or new rosette leaves bright green and without hairs on the upper surface or both).
