Moneywort forms mats of laterally branched stems and can be easily identified by the smooth, glandular dots on the surface of its leaves. This broadleaf weed also has short petioles and stems that root at the nodes, producing a shallow root system. Moneywort is sometimes sold in nurseries as a ground cover. Moneywort also has bright-yellow flowers that are produced individually on stalks in the leaf axils.
Moneywort thrives in moist soils along streams, riverbanks, ditches and roadsides. This broadleaf weed can be found throughout much of the continental United States.
Proper cultural practices, such as proper mowing and watering, can help prevent Lysimachia nummularia by creating dense grass, which inhibits this broadleaf weed’s ability to grow. Physical removal (i.e., pulling weeds) can be effective, though you run the risk of spreading the seeds to additional areas of your lawn.
