Potentilla anserina subsp. pacifica

Pacific silverweed, Pacific Silverweed

Family: Rosaceae · Type: perennial · Native

Pacific silverweed is a California native perennial found in coastal bioregions including northern, central, and southern California Coast Ranges in coastal wetlands, often brackish, at elevations generally below 150 meters. Flowering from March to October, this plant produces yellow flowers approximately 8 to 20 millimeters across with delicate, rounded petals. Growing with spreading stems 10 to 50 centimeters long that sprawl across wet ground, it forms dense ground-covering clusters. Its compound leaves are nearly glabrous, composed of 10 to 50 millimeter leaflets arranged in a pinnate pattern with a soft, silvery-green appearance. The plant produces numerous pistils, typically 20 to 200 per flower, which contribute to its robust reproductive strategy.
