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.

It was formerly classified in the genus Potentilla as Potentilla egedei. It is considered a member of the Argentina anserina species aggregate, or is alternatively treated as a subspecies of A. anserina by some botanists.

Eged's Silverweed is a low-growing herbaceous plant with creeping red stolons up to 80 cm long. The leaves are 10–40 cm long, evenly pinnate into in crenate leaflets 3–5 cm long and 2 cm broad, thinly covered with a few silky white hairs. The sparsity of the hairs is a useful distinction from A. anserina, which is more densely hairy.

The flowers are produced singly on 5–15 cm long stems, 2–3.5 cm diameter with five yellow petals. The fruit is a cluster of dry achenes.

<i>Potentilla</i> Genus of flowering plants in the rose family Rosaceae

Potentilla is a genus containing over 300 species of annual, biennial and perennial herbaceous flowering plants in the rose family, Rosaceae. They are usually called cinquefoils in English, but they have also been called five fingers and silverweeds. Potentilla are generally only found throughout the northern continents of the world (holarctic), though some may even be found in montane biomes of the New Guinea Highlands. Several other cinquefoils formerly included here are now separated in distinct genera - notably the popular garden shrub P. fruticosa, now Dasiphora fruticosa.

<i>Argentina anserina</i> Species of flowering plant in the rose family Rosaceae

Argentina 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. The reclassification remains controversial and is not accepted by some authorities. It is a species aggregate which has frequently been divided into multiple species.

<i>Dasiphora fruticosa</i> Species of flowering plant in the rose family Rosaceae

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 a disputed name, and the plant 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, and widdy.

<i>Argentina pacifica</i> Species of flowering plant

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.

<i>Potentilla hickmanii</i>

Potentilla hickmanii is an endangered perennial herb of the rose family. This rare plant species is found in a narrowly restricted range in two locations in coastal northern California, in Monterey County, and in very small colonies in San Mateo County. This small wildflower, endemic to western slopes of the outer coastal range along the Pacific Ocean coast, produces bright yellow blossoms through spring and summer.
