Hardscape in Your Landscape

Hardscape is the backbone of the landscape. Stone, wood and metal features enhance the plants and help organize and define garden spaces. Sidewalks, walls, stairways and fences should arise not merely out of function but with an eye to aesthetics. Using focal points with fountains, benches, urns, and statuary complete the picture.

Whether you inherited these plants from the previous owner or created your own design, do you imagine having a more inviting landscape; one that you see virtually every day? Let’s explore the possibilities!
