Weed or shady groundcover?
Whether or not horseherb (Calyptocarpus vialis) is a weed really depends on your own view about your lawn. If you have shade, then you probably already have this native creeping into your lawn. It may be frustrating, but its presence is a signal that you probably have too much shade to successfully grow turfgrass. Some homeowners actually buy horseherb and plant it as a shade groundcover. As it’s easy to grow, low-maintenance and tolerates some minor foot traffic, it can be a handy solution to a thinning lawn. Horseherb will spread and produces tiny yellow flowers throughout the growing season.
