Potentilla thurberi A. Gray
Rosaceae (Rose Family)
USDA Symbol: POTH2
Scarlet cinquefoil is a perennial of rich, conifer forests. Its leafy stems are usually at least a foot tall. Basal leaves are palmately compound, with five to seven leaflets. 1 or several leafy branched stems bearing loose clusters of long-stalked, rich, deep crimson flowers. Five-petaled flowers are rose-red to dark-red.
The rich red, darkest in the flowers center, seems to have a velvety glow; the surface is dull but the color intense. A second Potentilla species with reddish flowers, Purple Cinquefoil (P. palustris), is relatively humble, with tiny, dark red petals between larger, dull red sepals; it grows in bogs across North America, extending south in the West to northern California and Wyoming.
