[Wikipedia] Description, Habitat: Argentina anserina (synonym Potentilla anserina) is a perennial flowering plant in the rose family, Rosaceae. It is known by the common names silverweed, common silverweed or silver 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.[2] The reclassification remains controversial and is not accepted by some authorities.[1][3][4][5] It is a species aggregate which has frequently been divided into multiple species.[6][7] Description Silverweed is a low-growing herbaceous plant with creeping red stolons that can be up to 80 cm long. The leaves are 10 to 20 cm long, evenly pinnate into in saw-toothed leaflets 2 to 5 cm long and 1 to 2 cm broad with 6 to 14 teeth per side, covered with silky white hairs, particularly on the underside. These hairs are also present on the stem and the stolons. These give the leaves the silvery appearance from which the plant gets its name. Each leaf is borne on a channeled petiole up to 5cm in length with a long sheathing base.[8] The flowers are produced singly on 5 to 15 cm long stems, 1.5 to 2.5 cm diameter with five (rarely up to seven) yellow petals. The fruit is a cluster of dry achenes. Habitat 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. (link added by Mary Ann Machi)
