Potentilla simplex
Alternative names: Common Cinquefoil, Old field five fingers
French: Potentille simple

Old Field Cinquefoil is a low-growing native plant that brings a splash of sunny yellow to dry, open habitats from late spring to mid-summer. Its small, buttercup-like flowers are a great way to brighten up sandy patches, pathways, or naturalized areas in a yard or garden.

This species is well adapted to sandy, well-drained soils, and thrives in full sun. It is drought-tolerant, making it a good choice for rock gardens, dry meadows, or wildflower lawns. Although relatively uncommon in Quebec, it can be found in sandy meadows, prairies, and rocky outcrops throughout the Ottawa Valley.

Potentilla simplex spreads by stolons (above-ground runners), making it an excellent groundcover for naturalizing. It forms low, spreading mats of foliage that help suppress weeds and support native insects, especially small bees.
