Natural stone is a natural fit in the landscape, serving to complement and balance the ever-changing nature of the living trees, shrubs, garden plants and lawns that make up a yard's softscape.

Natural stone makes an effective and beautiful landscape materaial for retaining walls and raised planting beds.

As a hardscape building material, rock has undeniable virtues. Available in a huge range of sizes, colors, patterns and textures, stone is perhaps the most durable building material you can use — it may well outlast every other building material in your home.

The secret to effective design with stone is to use indigenous stone products native to the area, and to use them in the landscape in a manner that seems natural for the geographic region. For example, in the desert Southwest, red sandstones are a natural choice for a paving material, while in the far Northeast, the same patio space will look natural if paved with slabs of the granite that is so prevalent. In the bluff country of the Midwest, on the other hand, a terraced retaining wall garden made of large slabs of limestone mined from the local hills will lend a feeling of natural familiarity to a home landscape.

The style of the home can also dictate the type of stone. A residence that has an authentic Italian villa style can effectively use marble, which might be ill-suited to a traditional ranch-style rambler.

Here are some of the common ways natural stone can be used in the landscape.

Paving Surface for Pathways and Patios

Natural stone slabs can make a gorgeous paving surface for patios, pool decks, or walkways.

Natural stone in cut tiles or thin slabs makes one of the more elegant and premium paving surfaces available for patios or pathways. Natural stone says "class" in a way that brick or decorative concrete can't approach.

Cut stones or thin slabs can also be used for cobblestone pathways; for a more rustic pathway, use finer gravels, possibly with larger stones for the borders. A rustic pathway of this type is best designed with winding, natural flow. Use the stone pathway to lead guests to different garden areas or to a seating area away from the house.

Stairways and Garden Steps

Slabs of stone make and effective and attractive stairway to span different levels of a landscape.

Garden steps are given a big touch of elegance when they are made from natural stone, such as large pieces of cut limestone or granite mortared together. More rustic steps can be formed with raw flat stones placed to approximate the position of more formal stairs.

Garden stairs are best designed with steps that are broad and wide, but relatively short in height. Where possible, the choice of stone should echo materials found elsewhere in the landscape. For example, if a patio is constructed of limestone flagstones, use thicker limestone slabs in a similar color and texture for the garden steps.

Terraces and Retaining Walls

Natural stone makes a very durable retaining wall.

Slabs of cut limestone, granite or other hard stone make excellent retaining walls and landscape terraces. Installed correctly (and this requires careful engineering and installation), a stone retaining wall will outlast any wall made of timbers, concrete block or even poured concrete.

A terrace or retaining wall is very labor-intensive to construct, and proper drainage is critical to its long life. Stone walls can be dry-set without mortar, or installed with mortar filling the joints.

Garden Walls

As with retaining walls, natural stone also makes a great building material for freestanding garden walls. Here, it's especially useful to build with stone that is native to your area — both because of cost, and because walls built with native stone will look much more natural.

In New England, for example, the classic colonial garden walls were generally built from the many tons of stone cleared from agricultural fields — and to this day, that's a style that looks most consistent. In the Midwest, it was small rounded boulders, smoothed and hewn by glacial action, that became the prime building material for landscape walls. In the desert Southwest, red sandstones are a good choice for stone garden walls.

The use of raw gravel and weathered beach stone as a "mulch" to cover the ground beneath beds of shrubs and landscape plants was all the rage for some time, although now many homeowners are digging out that gravel to replace it with a more aesthetically pleasing groundcover mulch — or better yet, with living groundcover plants.

Still, there is a perfectly good role for smaller aggregate stone in some applications, such as in a region where the prevalence of streams or rocky beaches make beds of gravel in a landscape seem like a natural extension of nature. River rock also makes a good groundcover for a rain garden.

Decorative Water Features

Decorative water features are often major landscaping

Natural stone boulders and rocks can form the heart of a custom-built fountain or pond structure, or can be used to dress up and accent prefabricated ponds. Achieving a natural look is no easy matter with a stone water feature, and homeowners may want to consult a professional designer to create such a look. It generally requires a considerable amount of earth-moving.

Commercial fountains and bubblers made from carved and bored stone with small water pumps are also available, providing all the appeal of a stone water feature in a manageable size.

Accent Stones

Accent stones need not be huge, as in this example.

All by themselves, a boulder or group of boulders can make an eye-catching accent in the landscape. Sizes can range from relatively small rocks, 50 to 100 pounds artfully placed among a well-designed garden, to enormous boulders weighing many hundreds of pounds that serve as the central focal point. This technique must be used carefully, though. One homeowner may love a large, striking boulder, only to later find that potential home buyers find it to be not to their taste. Consult a real estate professional or landscape designer if you're considering a large-scale boulder for your landscape, because once a 1,000-pound boulder is placed in your yard, it is no easy matter to move it.

Individual accent rocks work best when integrated into plantings, such as when used as part of shrub island or large garden bed. Partial burial of a boulder or large stone to mimic the look of a natural outcropping will look more pleasing than one simply placed onto a landscape.

Rock Gardens

Rock gardens can take many forms—here, a heap of small smooth boulders is planted with mint.

A rock garden creates a focal point in the landscape and can be built to just about any scale you want — from fine gravel used as a bed for desert succulents to piles of boulders with ornamental specimens planted in every crevice and crack. Some rock gardens don't even include plants at all but are simply collections of various types and sizes of rock, but more often the stone is the backdrop for plantings. Certain types of gardening themes are better suited than others to the use of rock gardens, such as desert gardens, alpine gardens and Japanese gardens.

Rock gardens are especially appropriate on sloped landscape sites, but they can also be used simply to add a focal point to an otherwise mundane landscape.
