- Description
-
Horseherb is a shade-tolerant ground cover in the daisy (Asteraceae) family that is typically found in woodlands, roadsides, meadows, and disturbed sites. In the US, it is native to Alabama, Florida, Louisiana, Mississippi and Texas, and has been introduced into many other states.
It grows 6 to 12 inches tall and will spread with underground stolons in ideal conditions. It prefers shade to dappled shade in well-drained sandy soils but will adapt to more sun. Propagation is typically done through root cutting or division. It can be grown from seed, however, seed is difficult to collect in large quantities.
Tiny yellow flowers dot the bright green plants from spring to summer with their nectar attracting small butterflies.
Use it as a replacement for grass in dry, shady locations where other grasses cannot grow. For others, it can be seen as a nuisance, competing with your manicured lawn and beds. It makes an excellent ground cover for sloped locations.
Insects, Diseases, and Other Plant Problems: Root rot can occur from too wet soils. Plant struggle with heavy leaf litter from upper canopy plants. Can be weedy
