Argentina anserina is a synonym of Potentilla anserina L., the accepted name of a perennial flowering plant in the rose family Rosaceae. It is known by the common names "silverweed", common silverweed or silverweed cinquefoil. 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 originally placed in the genus Potentilla by Carl Linnaeus in his Species plantarum, edition 1, (1753) but was reclassified into the resurrected genus Argentina by research conducted in the 1990s. It is a species aggregate which has frequently been divided into multiple species. The reclassification remains controversial and is not accepted by some authorities.
