Potentilla reptans is becoming widely introduced in North America, though not fully naturalized in some of the states indicated here. It may be confused with P. canadensis and P. simplex, but, in addition to the characters highlighted in the key, P. reptans tends to have more crenately toothed leaves than the more sharply toothed leaves of the native species. The plant has a history of medicinal uses similar to that of P. erecta. The cultivated double-flowered form is sometimes found established in weedy places.
