Common types of landscaping rock include river rocks, lava rocks, crushed stone and gravel, Mexican beach pebbles, bull rock, and large boulders. The best type depends on the project.
River rocks are often used to edge garden beds, creating a visual boarder, keeping mulch in place, and preventing soil erosion.
Decorative lava rocks come in red, black, and gray colors, and provide a lightweight alternative to mulch.
Bull rock is commonly used for drainage, rock gardens, driveway and foundation boarders, and xeriscaping.
Mexican beach pebbles are great for driveways, walkways, planters, water features, and backyard ground covering where people may walk around barefoot.
