A focal point in the middle of the green area circled by the driveway creates the base of the landscaping design. Ideas include a water feature, large boulder, flowering tree or raised flower bed made from retaining wall bricks. The central landscaping feature adds height to that area. The rest of the landscaping is usually lower or gradually gets lower as it fans out from the tallest feature. Choose a focal point that fits with the rest of your landscaping. For example, if you have a natural or rustic landscape, a large boulder is a suitable focal point.
A border along the horseshoe driveway helps define the pathway. A short retaining wall offers clean lines to the area. Line the inner circular area with the retaining wall to define that area. You also have the option of adding a retaining wall along the outer edge of the driveway. For a more natural look, use hedges planted along the edge of the driveway. A similar option is to plant flowers or other greenery along the edges. If the driveway is narrow, set the border several inches away from the edge so you have enough room to open the doors and get out of your vehicles comfortably. Keep the border short so it doesn't obstruct views when people are entering and exiting the driveway.
The entrance of the driveway gives you another landscaping option. For a living entrance marker, plant short shrubs or other plants. Using lampposts on either side of the driveway entrance and exit is another option that helps illuminate the end of the driveway at night. Other ideas include a boulder, rock garden, short accent fences or archway that extends across the entire driveway entrance area.
Additional accents round out the landscaping of the horseshoe driveway. Flowers work well as accents because they add color to the area, creating a welcoming display for guests. Blend in a mix of flowers of different heights, colors and blooming seasons to keep the display interesting. Smaller rocks mixed in with the landscaping add variety to the colors and textures.
