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.
The list might include evergreen trees of hollies, cherry laurel, tree ligustrum, loquat, myrtle oak, sand live oak, and sweet acacia plus deciduous selections of Chinese elm, red bud, river birch and winged elm. Most of these grow less than 40 feet tall and not as wide.
