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.
Defined as plants that retain their leaves year-round, evergreens add a bright spot of color to a winter landscape. Conifers, like pine, spruce, cedar and fir are what typically come to mind when we think of evergreens but magnolia, hollies and eucalyptus trees are also evergreens. few other plant types are often mistaken for true bulbs because they grow the same way.
