The leaves bear some similarity to those of : Salad Burnet and Fodder Burnet, but the leaves on Silverweed are more ovate and sometimes silvery.

Uniquely identifiable characteristics : a 5-petalled yellow flower with singly-pinnate leaves that have quite distinct saw-tooth teeth. Sometimes these leaves are silvery on the underside, and fewer times silvery on the topside too, but never silvery on only the top-side. The silveriness is imparted by silky white hairs on the leaves and the stems.

Distinguishing Feature : The saw-toothed leaves which are sometimes silvery and the 5-petalled yellow flowers. Red stollons spread over the ground which root at intervals. In the 1990's it was reclassified from genus potentilla to argentina and is now called argentina answerina.

Silverweed likes to grow in quite damp ground, even grassy roadsides with running water in the gutter.
