Low-growing perennial herb spreading by stolons, forming mats up to 10 cm tall. Features compound leaves with silvery undersides and solitary yellow flowers blooming late spring to mid-summer. Prefers moist to wet soils and full sun to partial shade. Often found in coastal areas, tolerating salt spray. Useful for erosion control in wet areas and as a groundcover in rain gardens. Provides food for various waterfowl. Also known as Silverweed for its distinctive leaf coloration.

Phenology: New growth begins mid-May. Leaves fully developed by June. Blooms June through August. Seeds mature August-September. Foliage semi-evergreen, dying back partially in winter. Spreads by runners during growing season.
Wildlife Value: Seeds and foliage eaten by waterfowl; provides cover for small mammals and ground-nesting birds; flowers attract small native bees
