Silverweed
Potentilla anserina
  
About Silverweed (Potentilla anserina) 7 Nurseries Carry This Plant Argentina anserina, also known as common silverweed, silverweed cinquefoil or just "silverweed", is a flowering perennial plant in the rose family Rosaceae. It is native throughout the temperate Northern Hemisphere, often on river shores and in grassy habitats such as meadows and road-sides. The plant was formerly classified in the genus Potentilla but was reclassified into the resurrected genus Argentina by research in the 1990s. It is a species aggregate which has frequently been divided into multiple species. Silverweed is most often found in sandy or gravelly soils, where it may spread rapidly by its prolific rooting stolons. It typically occurs in inland habitats, unlike A. egedii, which is a salt-tolerant coastal salt marsh plant.
