Common Rock Sizes for Landscaping

Fines

• This type of rock aggregate is ideal for using in pathways. Comprised of a mix of rock particle sizes 1/2-inch and smaller, fines will pack down to a reasonably stable surface if confined by an edging.

Pea Gravel

• This small, smooth gravel, available in variety of colors, is striking as a mulch or turf replacement. Pea gravel's round shape and small size are difficult to hold in place, making them a poor choice for pathways.

River Rock

• Pea gravel's larger cousin, river rock plays a role as an edging material, turf replacement or mulch. River rock can be used alongside pea gravel of a similar color to create a pleasing contrast in textures.

Flagstone

• These wide, flat rocks can be fitted together to create pathways or walls. Try tilting small flagstones on their side for a rustic edging.

Boulders

• Large and eye-catching, boulders add visual appeal and architecture to a garden design.
