Xeriscape is notzero-scape. Even if you'd like to use rock mulch for your yard, there are plenty of plants that grow well with the extra heat. Rock mulch can be great for areas with high winds where wood mulch may not stay put. Rock is used throughout this landscape, and is planted with trees, shrubs and perennials that can tolerate the extra heat. This yard has a slight slope, so a small rock wall was installed in order to flatten out the planting area near the front door. This also helps add dimension and break up the large space.
