Black Medic

Symptoms

With its three leaflet clover like leaves, this legume is often confused with white clover. Low growing, with trailing, slightly hairy stems, it produces clusters of small, bright yellow flowers in late spring to early summer.

Black medic is common in lawns from May through September. It is especially prevalent in dry soils where turf is spotty and in high-phosphorus soils. Though an annual, it can be as persistent as a perennial.
