Landscape Smart host Ken Bastida (left) discusses design ideas with homeowners Steve and Joanie Wynn (right) and landscaping expert Jamie McMurray.

Northern California homeowners Steve and Joanie Wynn have a small brick patio in their backyard, but the view is of an ugly, overgrown hillside. The perfect solution, landscape designer Jamie McMurray says, is to install a meandering dry creek bed, with meadow plantings on the banks and a container water garden at the base to lend the sound of a babbling brook. The Wynns love the idea; it will give them a place to read and relax while listening to the soothing sound of water.

Within three days the Wynns will look out onto their own private "creek," complete with the sound of running water.
McMurray explains that it's important to design the creek bed so that it winds and curves, just as brooks do in nature. Also, he advises using rocks of varying sizes to form the bed, and carefully hiding the beginning of the creek so that it curves out from behind a tree or a group of plantings. The total cost of this project would be $3,500 if done professionally, says McMurray; with the help of the homeowners, the cost can be pared to $750, and that includes plants, rocks and boulders, and supplies for the water garden.In terms of difficulty, the project is rated a 5 on a scale of 1 to 5. "We're talking about two tons of rocks and boulders," says McMurray. He recommends bringing in help to haul and place the large stones for the creek bed.

Landscaper Jamie McMurray found some old stumps on the property and made them into steps to add to the natural, wild feel of the redesign.
  • Use the dirt removed from the trench to build up the sides of the creek, forming banks.
  • Lay down a strip of weed cloth to prevent plants and weeds from emerging in the trench (figure B). Use special staples to hold the cloth in place.
  • Cover the weed cloth with a layer of sand to form a solid base for the rocks.

    Step Two: Laying the Stones

    Now it's time to lay the rocks and stones that will form the dry creek bed. Use a variety of sizes, and try to place them in a way that imitates nature; that is, put larger, heavier stones on the sides of the creek bed (figure C), and place smaller stones so that they "flow" down the middle of the creek.

    Avoid organizing the rocks in any pattern, and when you reach the lower end of the dry creek bed, spread fine, gold-colored decomposed granite (figure D) to create the look of natural sediments.

    Low-maintenance verbena (Verbena bonariensis) is hardy in Zones 7-11, blooms summer through fall and reseeds freely.

    Miscanthus (Miscanthus sinensis) is an ornamental grass that will create good focal points in the meadow garden.

    Long-blooming Mexican primrose (Oenothera berlandieri) has a spreading habit and might need to be trimmed back periodically.
    Planting Plan

    With the rocks in place, it's time to fill in the meadow. Again, the idea is to create a natural look (McMurray calls it "planned wildness"). In California that would mean using plants that are native and drought-tolerant. Here is McMurray's strategy:
  • Keep the design simple; repeat colors, forms and textures within the given area.
  • Make sure both sides of the creek bed are balanced.
  • Create focal points by placing a few unusual plants, such as large ornamental grasses, at the top and bottom of the bed.
  • Choose a color palette: warm colors (oranges, reds, yellows) are lively and can make a large area feel intimate; cool colors (blues, purples, greens) are relaxing and create the illusion of depth.
  • McMurray's plant choices for the Wynns' new meadow include verbena (Verbena bonariensis), miscanthus (Miscanthus sinensis), Mexican primrose (Oenothera berlandieri), yarrow (Achillea x taygetea) and black-eyed Susan (Rudbeckia fulgida).
  • The Finished Project

    Take a look at the "before" and "after" photos. The Wynns' backyard has been transformed from a weedy, overgrown area to a natural-looking meadow that looks as if it has always been there. The dry creek bed provides just the view they wanted from their brick patio, and the container water garden completes the illusion of a trickling brook.
