You can totally use large landscaping rocks for steps, chill spots, cool sculptures, or just to make a statement. You can also install them on any sunken concrete base and use them as a backdrop for your water features, drops or ponds. Sunken rock gardens and plant beds is another wonderful idea! Just fill the small rock depressions with sand and potting mix and place in small, drought-resistant succulents for a unique rock garden!  You can also use large landscaping rocks for retaining walls, plant borders, and edging. They are super sturdy and heavy, so the wind won't mess up your plant setup!
