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]
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 saw-toothed leaflets 2–5 cm long and 1–2 cm broad with 6–14 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 5 cm in length with a long sheathing base. [8]
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.
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.
The plant was put in shoes to absorb sweat. It was formerly believed to be useful for epilepsy, and that it could ward off witches and evil spirits. [9]
The plant's roots were eaten by some Native American tribes. [10] It has been cultivated as a food crop for its edible roots, which resemble parsnips. [11] It may also become a problem weed in gardens.
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. [12] 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. [13]
The pre-Linnaean name anserina means "of the goose" (Anser), either because the plant was used to feed them or because the leaves resembled the bird's footprints. In Sweden, the flower is called gåsört (goose-wort).
A rich folklore has developed around Silverweed. The plant bears the common name of richette in French, being rich through both silver and gold.
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. [14]
Argentina anserina achenes are rather rare in Pliocene fossil floras of the East Europe but common in the Pleistocene. [15]
Potentilla is a genus containing over 300 species of annual, biennial and perennial herbaceous flowering plants in the rose family, Rosaceae.
Potentilla erecta is a herbaceous perennial plant belonging to the rose family (Rosaceae).
Ranunculus repens, the creeping buttercup, is a flowering plant in the buttercup family Ranunculaceae, native to Europe, Asia and northwestern Africa. It is also called creeping crowfoot and sitfast.
Dasiphora fruticosa is a species of hardy deciduous flowering shrub in the family Rosaceae, native to the cool temperate and subarctic regions of the northern hemisphere, often growing at high altitudes in mountains. Dasiphora fruticosa is still widely referenced in the horticultural literature under its synonym Potentilla fruticosa. Common names include shrubby cinquefoil, golden hardhack, bush cinquefoil, shrubby five-finger, widdy, and kuril tea.
Geum urbanum, also known as wood avens, herb Bennet, colewort and St. Benedict's herb, is a perennial plant in the rose family (Rosaceae), which grows in shady places in the temperate regions of Eurasia and North America.
Filipendula vulgaris, commonly known as dropwort or fern-leaf dropwort, is a perennial herbaceous plant in the family Rosaceae, closely related to meadowsweet. It is found in dry pastures across much of Europe and central and northern Asia, mostly on lime.
Argentina (silverweeds) is a genus of plants in the rose family (Rosaceae) which is accepted by some authors, as containing 64 species, but classified in Potentilla sect. Leptostylae by others.
Argentina egedei, known as Eged's silverweed, is a flowering perennial plant in the rose family, Rosaceae. It is a salt-tolerant plant native to arctic and cool temperate coasts of the Northern Hemisphere, most commonly growing in salt marshes. The southern limits of the range are California and Long Island, New York in North America, and the Baltic Sea and coastal eastern Siberia in Eurasia. It is also sometimes called "Pacific silverweed", though this usually refers to Argentina pacifica and in any case does not describe the range of Eged's Silverweed well.
Potentilla reptans, known as the creeping cinquefoil, European cinquefoil or creeping tormentil, is a flowering plant in the family Rosaceae.
Potentilla indica, known commonly as mock strawberry, Indian-strawberry, or false strawberry, often referred to as a backyard strawberry, mainly in North America, is a flowering plant in the family Rosaceae. It has foliage and an aggregate accessory fruit similar to that of a true strawberry. It has yellow flowers, unlike the white or slightly pink flowers of true strawberries. It is native to eastern and southern Asia, but has been introduced to many other areas as a medicinal and an ornamental plant, subsequently naturalizing in many regions worldwide.
Argentina pacifica, sometimes called pacific silverweed, silverweed cinquefoil, or simply silverweed, is a low-growing perennial (6") with pinnately compound green leaves with silvery undersides. It is a member of the species aggregate known as Argentina anserina or Potentilla anserina. The yellow, saucer-shaped flowers appear late spring through summer. Pacific silverweed spreads very quickly in moist areas. Preferring salt marshes, river estuaries and shorelines, they are often seen growing alongside springbank clover. They need sun and regular water.
Packera obovata, commonly known as roundleaf ragwort, spoon-leaved ragwort, roundleaf groundsel, or squaw-weed, is an erect perennial herb in the Asteraceae (aster) family native to eastern North America. It was previously called Senecio obovatus. Basal and lower leaves are obovate with toothed margins, while upper leaves are pinnately divided. The ray flowers are yellow and the disk flowers orange-yellow, the inflorescences being held well above the foliage.
Sibbaldiopsis is a genus in the plant family Rosaceae. This genus only contains a single species: Sibbaldiopsis tridentata, formerly Potentilla tridentata. Commonly, its names include three-toothed cinquefoil, shrubby fivefingers, and wineleaf. Systemic phylogenetic work has placed S. tridentata within Sibbaldia as Sibbaldia retusa.

In English it is sometimes called Tibetan tree peony or Ludlow's tree peony. It has pure yellow, slightly nodding, bowl-shaped flowers, and large, twice compounded, light green leaves.
Potentilla villosa is a species of flowering plant in the rose family, Rosaceae. Its common names include villous cinquefoil, northern cinquefoil, and hairy cinquefoil.
