This cinquefoil, Potentilla norvegica, may be annual or perennial. It produces a basal rosette of leaves from a taproot, then a green or red stem growing erect up to about 70 centimeters in maximum length. The leaves are usually ternate, divided into three leaflets. Each leaflet may be up to 5 centimeters long and is widely lance-shaped with toothed edges.
The inflorescence is a cyme of several flowers. Each flower has five rounded yellow petals no more than 4 millimeters long on a calyx of hairy, pointed sepals with reddish tips.
