This spreading groundcover is particularly effective on sites that have problems with erosion, since the rhizomes grow to form a mat that helps hold soil in place.

Perennial peanut is evergreen in frost-free areas of the state. In colder parts of the state, it will drop its leaves, exposing its brown rhizomes. If you're using perennial peanut as a lawn substitute, you can overseed the area with ryegrass to keep the area looking green throughout the winter.

Some of the best features of perennial peanut are its resistance to nematodes, pathogens, and drought. Plus it requires little fertilizer.
