Flagstone

Flagstone is a hard, natural stone with uniform internal layers that split into flat, thin pieces. It is best known for its color and texture as each piece has its own special attributes and characteristics. It can come in beautiful shades of blue, gray and lavender or shades of tan, brown and red. Flagstone is commonly used in the landscape as a patio, pathway or stepping stone. Often, landscape designers will combine different shapes, sizes or color waves to create interesting and unique surfaces.  

We source our flagstone from Pennsylvania and carry it by the piece or by the pallet in the following varieties:

  • Full color natural cleft: Rectangular in shape, full color natural cleft flagstone has flat, straight edges and subtle facial texture that’s created during the clefting process. This stone boasts a wide color range and is often considered a bit rustic in texture making it an excellent choice for farmhouse and cottage landscape designs. 
  • Full color thermal: Rectangular in shape, full color thermal has flat, straight edges that are sawn and torched on all six sides to bring out an even texture. This type of flagstone is great to install around a pool or as steppers on a walkway, providing a modern, elegant look. Because of its even texture, thermal stone is also preferred for those with mobility challenges.
  • Blue select: Square shaped, blue select boasts a beautiful blue-gray hue with the slightest variation in color between pieces. It’s typically used in modern and contemporary landscape design projects.  
  • Irregular: Uniquely shaped stones with irregular edges that are 1 to 1½” thick, irregular flagstone puzzles together into an interesting pattern by the installer. These stones are sold by the pallet, weighing approximately 3,000 to 4,000 lbs. and covering 75 to 125 sq. ft. Irregular flagstone comes in colors of lilac, sandy taupe, dove gray and blue. The blue color wave is a tumbled stone, which results in a smoother edge. We also offer a variety called west mountain, which includes mixed shades of red, gray, brown and tan with reddish veins running through it.

Wall Stones

Primarily used as facing stones on retaining walls, these naturally occurring stones are made up of materials such as flint, granite, limestone and sandstone. They’re available by thickness and come in thin (1 to 3”) and regular (3 to 5”). We sell them by the quarter pallet, which weighs approximately 500 lbs and covers 3 to 5 sq. ft. A full pallet can weigh 2,800 to 3,200 lbs and covers 15 to 20 sq. ft. Along with retaining walls, these stones can be used to border planters, flowerbeds and patios, face bars and grill areas, adorn fire pits and construct waterfalls, benches or seating areas.

Belgian Blocks

Belgian blocks are naturally occurring stones that are quarried and shaped into rectangular and cubical forms. They are commonly used for edging, separating areas of your garden that you would like to be cleanly defined, such as a pathway or garden bed.

Stepping Stones

Stepping stones are rocks placed throughout the landscape to form a safe walking path. We carry natural stepping stones in 14 – 16” rounds, and aggregate stepping stones in assorted sizes and square and round shapes. Natural stepping stones are flat and contain quartz, giving them a particularly glittery appearance that is attractive in the sunlight as you walk across your yard. Aggregate stepping stones are composed of small river rocks held together by concrete. They come in shades of tan and brown to blue, gray, purple and white.

Engineered Stone

Engineered, or cultured stone is a man-made product created with concrete and dye to mimic the look of natural stone, but with consistent shapes and sizes. It also typically comes with a warranty–depending on the manufacturer–ensuring the life of the product pending correct installation. Today, engineered stone pavers are popular for the range of colors, patterns and shapes, with manufacturers offering a large assortment of contemporary patterns.

Flagstone-like Products

  • Blue mountain: Engineered and cast in the style of square cut flagstone. Because it’s man-made, Blue Mountain flagstone comes in different color options with each piece being a solid color with an even thickness.
  • Irregular blue mountain: Engineered and cast in the style of irregular shaped flagstone. Because it’s man-made, irregular Blue Mountain flagstone comes in different color options with each piece being a solid color with an even thickness.

Pavers

Beloved for its unique pattern and design options, Techo Bloc is an engineered stone production company that supplies everything from cultured patio slabs to stone steps, pavers, edging stones and wall caps in colors ranging from orange and red, to beige and brown, to black, gray and white. Our landscape design team is well versed in the product range and works daily to innovatively combine products to create unique landscape spaces. If you’re interested in exploring the product offering, browse their options online or pick up a free Techo Bloc magazine in our stores. 

If you’re seeking permeable pavers for your space, note that this can be accomplished using both natural and engineered stone products. Permeable pavers are laid in a way where each piece of stone is spaced to leave a joint or open ground between to soak up the moisture and limit the amount of water that runs off your property to mitigate flooding. With the many materials and layers of drainage required for permeable pavers, we recommend working with a professional installer. They will understand how to build an effective base layer with gravel, stone and landscape fabric and level the surface for a flat paver experience. If you are interested in installing permeable pavers, book a Full Service Landscape Appointment and we’ll be happy to walk you through your options. 

Edging products clearly define separate areas of your landscape, such as patios from garden beds or lawns from pathways. When it comes to choosing your edging product, it’s often a matter of personal aesthetic. For the most part, using edging in the landscape is optional and based on the look you want to achieve. It is required when installing hardscapes, such as a paver patio, walkway, or driveway as it keeps the stonework and gravel in place for years to come. We carry wooden, plastic, stone and metal edging options at our three locations of Merrifield Garden Center. We suggest coming to see our stone and edging experts to determine the perfect edging to use in any given landscape project.

Wooden Edging

Our wood edging options are made out of wood timbers, providing a natural look in the landscape. Each option can run in a single layer, or stacked to form a taller barrier. 

  • Pressure treated timber: This type of edging is made out of new wood. Before you take it home, our team will freshly cut it to size. It is also pressure treated so it will not rot over time. Pressure treated timber comes in the following sizes:
    • 4 x 6 x 8”
    • 4 x 6 x 12”
    • 6 x 6 x 8”
    • 6 x 6 x 12”
    • 6 x 8 x 8”
    • 6 x 8 x 12”    
  • Railroad ties: Previously used on railroad tracks, these ties are made of aged wood and provide a rustic look in the landscape. They are durable, inexpensive and much larger than our pressure treated timber. We do recommend using an alternate edging material when growing vegetables, herbs and fruits as the process used to treat railroad ties can result in chemicals leaching into the soil. 

Plastic Edging

Plastic edging is easy to work with and will typically stay in place for longer periods of time than other edging materials like aluminum and steel. It will not rust and is inexpensive. 

  • Valley View plastic edging: With a hollow, round tube across the top and a horizontal tab across the bottom, Valley View garden edging stays in place when you insert it into the ground and cover it with soil. It is made out of a plastic material and comes in a roll 20’ long by 4.5” tall. This type of edging is typically used to separate garden beds from turf or lawn.
  • Hammer Edge: This type of plastic edging has jagged teeth across the bottom and is sold in packs of panels equivalent to 18’ of coverage. You can use a plastic mallet to install this edging, pounding the jagged teeth into the ground. Hammer Edge is typically used for lining garden beds, separating them from your lawn or to keep gravel in place.  
  • Bulldog edge: Plastic bulldog edging is created from high grade plastic and features horizontal tabs along the bottom of the pieces, making this the preferred plastic edging material to use for hardscape projects.  

Metal Edging

While you can use metal edging like aluminum and steel for any edging project, it’s most commonly used to define hardscapes, such as walkways, patios or driveways. Metal edging is heavy and durable and beloved for its industrial look and feel. It comes in straight pieces with the option to add connectors and right angle corners. The ⅛” thick versions of aluminum and steel edges work well around slight curves. Since it’s wider than plastic, wooden and stone edging, metal edging is ideal for bordering areas that are taller, such as elevated patios or pool decks. When installing metal edging, we recommend hiring a professional as this type of edging is heavy and cumbersome, requiring special tools and bigger trucks to transport and install. 

  • Aluminum: Aluminum edging is available in bronze, green or black in 4” x 8’, 4” x 16’ and 5” x 16’ with the stakes sold separately. Depending on how long you want your edge, you can use connectors and right angle pieces to join the slabs together. 
  • Steel: Steel edging is available in black or brown in 4” x 10’, 6” x 10’ and 4” x 16’. We provide five stakes with your purchase, and you can purchase more if necessary. Depending on how long you want your edge, you can use connectors, end pieces and right angle attachments to join pieces together. 

Stone Edging

In addition to traditional wood, plastic and metal edging options, you can also use natural or engineered stones and bricks to create a more rustic edge around planting beds. We carry Belgian blocks in black, gray and pink in 4 x 4 x 8”,  5 x 5 x 9” and 10 x 4 x 7”. We also stock a selection of paver edging and other stone products in our stone yards. Stop by a Merrifield Garden Center location and ask to speak with our stone experts to see our in stock collection.
