Sunny spots in the landscape are great for flower gardens. Perennial and annual flowers provide a garden with color and fragrance. Some will even attract wildlife such as birds and butterflies. Many perennials and annuals do very well in full sun as they're able to tolerate the hottest summer days as well as the dry conditions of this environment. Planting a variety of perennials with different bloom times will provide your garden color from spring, through summer and into fall.
