A creeping perennial plant native to Eurasia and Northern Africa, Potentilla reptans has been naturalized elsewhere. Its trailing stems root at the nodes, and leaves are on long stalks. The plant blooms between June and August with yellow flowers that are about 2 cm in diameter and have five heart-shaped petals. Potentilla reptans, which can be easily confused with silverweed, often grows in crushed masonry in the South of England. The grizzled skipper butterfly favors the plant.
Alcoholic extracts from roots of Potentilla reptans showed a moderate antimicrobial activity against common wound pathogens.
Potentilla reptans can be an invasive weed in lawns and flowerbeds and difficult to eradicate, particularly when it competes with and infests established groundcovers. All of the taproots must be dug up, or the plant will reappear.
