The traits that make it popular for orchards and pastures also make it a good cover for low-maintenance areas, paths, home orchards, slopes, etc. It enriches the soil, and it's deep roots hold banks and slopes. It's stems can get somewhat long--3 feet or so--but mostly lie down and so the effective height is about a foot to 18". One of the plants that can cope with hardpan.
