Ground Covers
Use ground covers where shade is too dense or the terrain is too rough for turfgrass. Many types of ground covers can provide color and texture differences in the landscape and keep soil in place.
Ground covers are less than 18 inches in height and generally require little maintenance once they are established. Some, such as mondo grass, resemble grass in growth form while others, such as sweetwilliams and violets, are grown as much for flower color as for the foliage.
Select ground covers to blend with the overall landscape plan. While the dark green of mondo grass or English ivy blends well with well-maintained bermudagrass or St. Augustinegrass, it contrasts sharply with carpetgrass or centipedegrass.
The following chart helps to determine how much square footage can be planted with 100 plants when spaced at various measurements.
