Argentina anserina
''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.〔(A key to the ''Potentilla'' complex )〕 It is a species aggregate which has frequently been divided into multiple species.
==Description==
Silverweed is a low-growing herbaceous plant with creeping red stolons that can be up to 80 cm long. The leaves are 10–20 cm long, evenly pinnate into in crenate leaflets 2–5 cm long and 1–2 cm broad, 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.
The flowers are produced singly on 5–15 cm long stems, 1.5-2.5 cm diameter with five (rarely up to seven) yellow petals. The fruit is a cluster of dry achenes.
