Calyx and corolla, 5-divided. 5 bractlets, often cut, lie between the sepals. Leaves, all from the root, pinnate, with from 7 to 21 leaflets and smaller ones in between, dark green above, silky white beneath. 2 or 3 feet long. June to August.
The broad, open, yellow flower grows on a scape from a bed of beautifully cut, handsomely colored leaves, which are green above, conspicuously white beneath. Like a strawberry plant, the silver weed spreads by jointed runners. Along the dunes bordering Long Island bays I have found this pretty potentilla, its leaves lapping the water. In salt or brackish marshes, banks of streams, very widely disseminated. (See illustration, p. 173.)
