Prune and shape evergreen shrubs to provide year-round hedges, ground covers and privacy screens in your yard. The scarlet firethorn (Pyracantha coccinea) and Chinese holly (Ilex cornuta) shrubs produce red-colored berries and dark-green leaves.
Basically these are plants that retain their leaves all year around. The leaves are usually green in color but there are certain evergreen shrubs that give off foliage of other colors like red, purple, orange, yellow and silver. A popular feature in all evergreen shrubs (in some case hybrids) is that they maintain a fixed small or medium heighs and have a clustered branch growth.
