Why Landscape Stones Are the Foundation of Great Outdoor Design

Landscape stones are decorative rocks used in outdoor spaces for pathways, borders, ground cover, water features, and countless other applications. They transform ordinary yards into beautiful, low-maintenance landscapes while solving practical problems like drainage and erosion.

Quick Answer: What You Need to Know About Landscape Stones

  • Types: Pebbles (small, rounded), gravel (crushed rock), cobbles (medium, 3-12″), boulders (15-30″+)
  • Popular Materials: River rock, lava rock, decomposed granite, flagstone, marble chips
  • Key Benefits: Low maintenance, weed suppression, improved drainage, long-lasting durability
  • Common Uses: Pathways, garden borders, dry creek beds, fire pits, water features
  • Coverage: One cubic yard typically covers 160 sq ft at 2″ depth
  • Cost Range: From budget-friendly gravel to premium decorative stones

The growing popularity of landscape stones reflects what homeowners and contractors already know: stone is one of the most versatile and practical materials for outdoor projects.

Whether creating a modern patio, a rustic dry creek bed, or simply replacing mulch, landscape stones offer durable solutions. They handle foot traffic, prevent weeds, improve drainage, and require less upkeep than grass or wood mulch.

The challenge isn’t if you should use stone—it’s which one to choose. With dozens of types, sizes, and colors, the right selection depends on the application. A smooth pebble perfect for a Zen garden is wrong for a driveway, while angular crushed stone ideal for a path might look too industrial for a cottage garden.

This guide breaks down everything you need to know: from understanding the difference between pebbles and boulders to matching stone types with design styles and calculating how much material your project requires.

Choosing the right landscape stones is key to a successful outdoor project. With a huge variety of types, styles, and uses, understanding each material’s nuances is essential. Natural variations in color and texture add to the stone’s charm, helping create unique landscapes.

When asked about the best landscaping rocks, we explain that the answer depends on your unique space.

Decoding the Language of Stone: Pebbles, Gravel, Cobbles, and Boulders

Understanding the language of stone size and shape is crucial for selecting the right material for the job.

  • Pebbles: Small, smooth, rounded stones (1/2″ to 2″). Their water-worn surfaces are popular for decorative accents, Zen gardens, or between stepping stones. Mexican Beach Pebbles are a prime example.
  • Gravel: Generally crushed, angular rock (1/8″ to 3″). Its angular nature compacts well, making it excellent for pathways, driveways, and drainage. We offer various types of Gravel.
  • Cobbles: Medium-sized, rounded stones (3″ to 12″). Their size and shape are ideal for natural features like dry creek beds, ponds, and waterfalls, or for borders. Explore our selection of Cobbles for your project.
  • Boulders: The largest landscape stones (12″+), typically 15″ to 30″ or more. They serve as dramatic focal points, natural seating, or structural elements in retaining walls. Find robust Boulders to make a statement.

Rounded stones (river rock, beach pebbles) are smooth and comfortable underfoot, great for paths and water features. Angular stones (crushed granite) interlock when compacted, providing a stable surface for driveways, high-traffic areas, and slopes.

Let’s explore some of the most popular types of landscape stones and their unique characteristics.

Stone Type Common Uses Design Style Permeability
Flagstone Patios, pathways, stepping stones, wall caps Rustic, natural, formal, transitional Low
Lava Rock Garden beds, fire pits, ground cover, drainage Rustic, desert, modern, contemporary High
River Rock Dry creek beds, borders, water features, ground cover Natural, rustic, Zen, coastal Medium
Decomposed Granite Pathways, driveways, patios, xeriscaping Natural, rustic, Mediterranean, modern High
Marble Chips Decorative ground cover, pathways, accents Modern, minimalist, formal, contemporary Low

Here are some other fantastic options:

  • Limestone: A sedimentary rock in various colors, limestone offers a classic look for walls, patios, and paths. Its outdoor suitability depends on its ASTM rating (Type III is best for exterior use).
  • Quartzite: Transformed from sandstone, this stone is incredibly hard and dense, making it a durable choice for flooring and decorative gravel. We have beautiful Quartzite options for your projects.
  • Field Stone: Naturally rounded stones found in fields, not quarried. They offer a rustic look perfect for garden walls, raised beds, or natural seating. Our Field Stone adds natural elegance.
  • Slate: This metamorphic rock splits into thin, flat slabs. Its water resistance makes it ideal for paving, tiles, and areas around water features. Gray slate chips are versatile for modern landscapes.
  • Granite: An igneous rock renowned for its hardness and durability. It’s a top choice for outdoor kitchens, flooring, accent boulders, and gravel, perfect for high-traffic areas.

Matching Stone to Style: Design Applications

Landscape stones can define and improve any design style, from sleek modern aesthetics to charming rustic retreats.

  • Modern Design: Use stones with clean lines and uniform colors like charcoal basalt gravel, polished Mexican beach pebbles, or white marble chips. They create dramatic contrast and pair well with minimalist plantings.
  • Rustic Aesthetic: Fieldstone, river rock, and decomposed granite provide earthy tones and irregular shapes for a rustic look. Use them for meandering Stepping Stones paths or dry creek beds.
  • Formal Gardens: For a structured look, use cut stone like limestone or precisely laid flagstone pavers. These materials complement manicured hedges and classic layouts. White marble chips also add timeless formality.
  • Japanese Zen Gardens: Smooth, rounded stones like Mexican beach pebbles or pea gravel are essential for creating calming raked patterns. Boulders are used as tranquil focal points.
  • Xeriscaping (Drought-Tolerant Landscapes): Landscape stones are ideal for water conservation. Decomposed granite, lava rock, and gravels reduce the need for thirsty lawns and suppress weeds, creating beautiful, low-maintenance landscapes.

Beyond overall style, specific applications benefit from particular stone types:

  • Pathways and Driveways: Pea gravel offers a comfortable, natural look for paths. Crushed bluestone or decomposed granite provide a stable, compacting surface for high-traffic walkways and driveways.
  • Garden Borders: River rock, cobbles, or even smaller boulders can neatly define garden beds, creating a clean edge between planting areas and lawns.
  • Retaining Walls: For structural support, we use fieldstone, large angular rubble stone, or cut stone to create robust and beautiful terracing on sloped properties.
  • Water Features: Smooth river rock and cobbles are perfect for lining ponds, waterfalls, and dry creek beds, creating a natural, serene environment.
  • Fire Pits: Lava rock is a popular choice for gas fire pits as it retains heat. Fieldstone or cut stone can be used for the pit’s structure, blending warmth and style.

From Plan to Placement: Practical Tips for Your Stone Project

A successful landscape stones project requires thoughtful planning. From calculating quantities to understanding maintenance, our goal is to ensure your vision comes to life smoothly.

Smart Selection: Key Practical Considerations

Before placing the first stone, several practical considerations can make or break a project. We encourage our customers in Scotts Valley, the Bay Area, San Francisco, and Carmel Valley to consider these points.Decorative natural stone walkway with river rock accents creating an elegant landscape pathway design.

  • Drainage: Drainage is paramount, especially with heavy rainfall. Coarse gravels and lava rock allow water to permeate the ground, preventing pooling. For dedicated solutions, Drain Rock is designed to direct water flow away from structures.
  • Weed Suppression: A key benefit of landscape stones is weed suppression. We always recommend laying high-quality landscape fabric underneath. This permeable barrier lets water through but blocks weeds, saving significant effort later.
  • Durability and Foot Traffic: Consider the area’s use. For high-traffic paths or driveways, angular crushed stone or decomposed granite compact well for a stable surface. Smooth river rocks can shift underfoot and are less ideal for primary walkways.
  • Slope Stability and Erosion Control: On slopes, angular stones or riprap are effective for erosion control, holding soil in place. River rock works on gentler slopes, while boulders provide major stability.

Calculating and Maintaining Your Landscape Stones

Once you’ve chosen your stone, you need to calculate the required amount. Getting this right saves time, money, and delays.

Calculating Quantity:
Use this formula to estimate how much stone you’ll need:
(Length in feet x Width in feet x Depth in feet) / 27 = Cubic Yards needed.

For example, for an area 10 ft long by 16 ft wide at a 2-inch (0.167 ft) depth:
(10 x 16 x 0.167) / 27 = 0.99 cubic yards. You would need about 1 cubic yard.

Here are some helpful coverage statistics:

  • One cubic yard of rock ground cover can cover approximately 160 sq ft at a 2-inch depth.
  • A 3/4 cu ft sack of rock ground cover can cover approximately 8 sq ft at a 1-inch depth.
  • Polished pebble landscaping rocks (44lb sacks) will cover approximately 5 sq ft at a 1-inch depth.
  • One ton of cobble or rubble stone can cover between 25-35 sq ft.
  • A full pallet of Mexican Beach Pebbles (3000 lb) provides 60-80 sq ft of coverage.

Some materials are sold by the cubic yard, while larger stones like cobbles and boulders are often sold by the ton. Our team can help you with conversions to ensure you order the right amount.

Maintenance Requirements:
One of the key benefits of landscape stones is their low maintenance, but “low” doesn’t mean “no.”

  • Rinsing Dust: Periodically rinse stones with a garden hose to remove accumulated dust and keep them looking fresh.
  • Removing Debris: Regularly rake or blow away leaves and twigs to prevent them from decomposing and creating a bed for weeds.
  • Weed Control: Even with landscape fabric, a stray weed might pop up. Spot-treating or hand-pulling them quickly will keep your stone areas pristine.
  • Sealing: For pavers or decorative slabs, applying Cleaners Sealers can protect from stains, improve color, and extend their life.
  • Topping Off: Over time, smaller stones may settle. You may need to occasionally add a fresh layer to maintain depth and appearance.
