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 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. It is a species aggregate which has frequently been divided into multiple species. The reclassification remains controversial and is not accepted by some authorities.
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.
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.
Cultivation and uses
Travelers visiting Tibet reported on the food use of the plant's root in the region. According to Pyotr Kozlov, who traveled in the Kham region in 1900-1901, Tibetans, who did not have any vegetables other than turnips, would often dig out roots of Argentina anserina (whose local name he gave as djüma), which could be easily dried and stored for later use. Kozlov even suggested that it would not be a bad idea for Russian peasants to do likewise, especially in famine years. The mission of Sarat Chandra Das to Tibet in the late nineteenth century reported that the root of the plant, under a Tibetan name variously transcribed as toma, doma or droma, was served cooked in butter and sugar at the New Year's celebrations in the Tibetan capital Lhasa.
Etymology and folklore
The pre-Linnaean name anserina means "of the goose" (Anser), either because the plant was used to feed them or because the leaves reminded of the bird's footmarks. In Sweden, the flower is called gåsört (goose-wort)
There is a legend that the Christ Child grew up and walked the roads of Palestine; and the yellow flowering plant of the dusty wayside with silvery fern-like leaves that lay flat on the ground has been called the Footsteps of Our Lord.
