Summary
Cow clover is a western North American native herb with a creeping rhizome and stems that are decumbent to erect, forming a low, evergreen ground cover; trifoliate leaves and dense pinkish-purple to magenta flower heads with white tips create a distinctive, showy display that attracts bees.
In cultivation, it prefers moist, well-drained soils in full sun to light shade and can serve as a durable ground cover or for erosion control, spreading by creeping rhizomes to form dense patches; it fixes nitrogen, supports pollinators, and has edible leaves, flowers, and rhizomes, with propagation by seed or rhizomes.
