Growing shrubs with colorful leaves as well as flowers keeps your garden display going year-round. Berries are another decorative feature shrubs can provide. Grow evergreen shrubs for structure and color through the winter, and select cultivars with leaves that also change color in spring and fall for variety and interest. Select shrubs that thrive in your landscape's existing conditions, such as full-sun sites -- which receive at least six hours' direct sunlight per day -- or partially shaded spots, which receive four to six hours of sunlight.
