Many clover varieties are used for ground cover due to their low-growing habits and low-maintenance needs. Many clover species are considered decorative ground cover due to their beautiful flowers and soft appearance. Clovers are nitrogen-fixing legumes that improve your soil and provide natural nutrients for other grasses and plants. Using Clover as a ground cover is environmentally-friendly and considered a "green lawn." White clover is most popular for ground cover in lawns, while red clover is most popular for parks, recreational areas, roadsides and pasture ground cover.
