Evergreens have the ability to keep their leaves all year round and remain with color, even during the winter. Evergreens also grow back each year to provide a long-lasting addition to the landscape. Trees and shrubs that are evergreens each have their own growing requirements. Tall evergreens like spruce, cedar and cypress trees provide a significant amount of shade outside. To promote fast growth for young evergreens or if you have a less than ideal planting site, fertilize the evergreens in early April with a complete fertilizer.
The Colorado spruce tree is an evergreen tree with blue-green needles. This evergreen has slow to medium growth and is appropriate for shading areas around the house, such as a backyard patio or front yard. Colorado spruce grows up to 90 feet high and 20 to 25 feet wide at its largest. It prefers full sun and moist, well-drained soil. It can tolerate a wide range of soil types, if necessary. The dense and narrow branches grow horizontally with stiff branches. The foliage is prickly with fruit cones ranging from 2 to 4 inches long. The Colorado spruce is more drought-resistant than any other spruce tree.
Holly, which works well as a shade shrub, has dark green foliage that grows between 30 and 60 feet tall and as wide as 35 feet. Hollies are slow growers that require sun to partial shade, as well as moist, well-drained soil. The upright and open structure of the plant is ideal for planting along the side of a home for shade and privacy. The irregular branches have small red berries in the fall that last through the winter. Small white flowers fill this evergreen in late spring and attract birds and butterflies.
This evergreen shrub has a broad shape that reaches up to 60 feet high and 15 feet wide. The yellow-green summer color turns bright yellow in winter to brighten up a winter landscape. The arborvitae requires full sun and can withstand a wide range of soil types and still flourish. The pyramid shape form is ideal along the side of a house or planted within an existing garden. Arborvitae also is appropriate for planting in rows along a driveway or front walk.
