Considering the various uses of pergolas, they not only serve as mere aesthetic design elements, but have other uses as well. When installed properly they are a great support for climbing plants and vines. This enhances the beauty of the place. The shade it offers to the patio or walkway is pleasant and if garden benches or swings are added underneath the pergola it will provide additional seating in the yard. The beauty and utility of the pergola depends upon the choice of the material. Wood pergolas are an attractive, natural choice for outdoor weddings during all seasons.
