Potentilla thurberi

Potentilla thurberi is found along higher elevation roadsides, moist creekbeds, and meadows. The deep red flowers have a "velvety" appearance. The relatively large and heavily veined serrate leaves are palmately divided. The pale anthers stand out against the darker central portion of the petals.
