Antennaria plantaginifolia (pussytoes)

Plaintain-leaved pussytoes or woman's tobacco is a low-growing, mat-forming perennial. It has fuzzy, gray-green leaves and small, white to pale pink flower clusters that look like a cat's paws (hence its common name). A good choice for groundcover in dry, rocky areas. Does not do well in fertle, humusy soils, especially if drainage is poor. Known for its drought tolerance and ability to supress weeds. Can also help to prevent erosion. Grows only 6" tall and spreads 1–2' wide. Blooms occur in mid to late spring, lasting about 2–3 weeks. 

Pussytoes is native to eastern North America. Host plant for the American painted lady butterfly, whose larvae appear from May to November. Attracts bees, butterflies, and other pollinators along with small mammals and songbirds. Generally avoided by deer and rabbits.
