When we talk about the design of a garden arbor or pergola, we're talking about the material as much as anything. The type of material used in making the structure will have a big impact on the look and use of the end product. There are three primary materials used for garden arbors and pergolas: wood, metal, and plastic. All three materials have their pros and cons, as we will explain.
Plastic arbors and pergolas can be purchased in almost every color imaginable. When choosing a vinyl unit, be sure to look for a plastic that is treated with a UV inhibitor, so it won't fade or discolor over time. Vinyl is a good choice if you want your end product to be relatively maintenance free, because it won't need to be stained or painted. A vinyl arbor or pergola typically lends itself to a clean and modern design. White vinyl can be an especially attractive choice for an outdoor wedding in the spring or summer.
Another consideration that will play into your design choice is whether the arbor or pergola will serve a functional purpose. Arbors and pergolas can be merely aesthetic design elements, placed in the corner of a yard or garden simply because they are visually pleasing. On the other hand, if you design them correctly, they can also provide an excellent support for climbing plants and vines. Consider designing an arbor or pergola with horizontal pieces beginning close to the ground and continuing upward. Climbing plants such as morning glory, trumpet vine, and clematis will quickly make the structure their new home, adding another dimension of beauty. Arbors and pergolas can also be used to shade a patio or walkway. If you build a structure large enough to span a deck or patio, consider planting grapes or some other vine that will quickly encompass the structure, as this will help shade the area underneath. Arbors and pergolas can also be designed with garden benches or swings underneath to provide an additional seating area in the yard.
There are as many different ways to design a garden arbor or pergola as there are uses for the structures; the choices are almost endless. By taking into consideration the type of material that best meets your needs and the purpose, if any, that the structure will serve, you will come up with a design that compliments your yard beautifully. Remember, an arbor or pergola is a large and important element in your landscape design. Take the time to choose a unit that's right for you, and you will be rewarded with a beautiful structure that will grace your garden for years to come.
