Potentilla californica, also known as California horkelia, is a species of flowering plant in the rose family.[1]
It is endemic to California, where it grows on scrubby coastal and inland mountain slopes, primarily in the California Coast Ranges and western Sierra Nevada foothills.
Potentilla californica is a clumping perennial herb[2] producing erect green stems variable in height from 10 centimeters to over a meter. The green leaves are up to 40 centimeters long and are made up of hairy, rounded, toothed leaflets each up to 6 centimeters in length.
The inflorescence holds solitary and clustered flowers, each with toothed bractlets and thick, pointed sepals. There are five small white petals. Flowers bloom April to July.
