Ground cover for the lawn or yard is the stuff that we put out to cover the ground. Most commonly in the suburbs it is grass, but it can be other plants (such as moss) or plant material (pine needles or mulch) or rocks and other decorative objects, such as a stream and bridge.
Rock gardens or other ground cover that does not require much water is becoming more popular in drier climates. Herbs and low-growing flowers can be pretty and fragrant. Some people prefer wild flowers and a more natural look than the manicured, grass lawns that were a point of pride for many in the 19th and 20th centuries.
Other alternative ground covers include ivy or low growing shrubs.
