Which of the following is a benefit of using ground cover in landscaping?

Using ground cover in landscaping primarily enhances the beauty of the landscape. Ground covers are often chosen for their aesthetic qualities, including their texture, color, and ability to create a lush, green carpet that complements the surrounding plants and features of the garden. They can also fill in bare spots and soften hard edges, creating a more visually appealing landscape.

In addition to their beauty, ground covers can provide other practical benefits, such as soil erosion control and weed suppression, which further contribute to a well-maintained and attractive outdoor space. They can also help to reduce maintenance by limiting the area that requires mowing or frequent care.

The other choices do not align with the primary advantages of using ground covers. Increased maintenance and heavy irrigation are generally negatives associated with traditional lawns rather than ground covers, which can often require less upkeep and water once established. Furthermore, restricting plant growth is contrary to the purpose of ground covers, which is to promote healthy growth in a designated area while covering the ground effectively.
