Grow For It! The bones of a garden: evergreens
UCCE Master Gardener of El Dorado County
Conifers, like pine trees and cedars, are not the only kind of evergreen plants. Evergreens are considered as any plant that does not go dormant and keeps its leaves year-round.
Evergreens take a leading role in a garden plan. Interspersed with deciduous trees and shrubs, evergreens bring “pop” to a garden in several ways: variegated foliage, height, architectural structure, bright flowers and more.
Examples of plants with architectural structure are Italian Cypress (Cupressus sempervirens), which have a columnar structure but can also be trained into an arch. Japanese Boxwood, such as Buxus microphylla japonica, “Winter Gem,” can be trained into a topiary adding interesting shapes and even whimsy.
Some evergreens provide year-round interest such as the Strawberry tree (Arbutus marina). It has a smooth red bark, blossoms of pink bells that look like dainty rain chains that then form into red fruit, hence the name. The Weeping Blue Atlas Cedar (Cedrus atlantica, “Glauca Pendula”) twists into a gentle corkscrew as it grows. It is quite dramatic in its own controlled and structured way.
Evergreen shrubs are also useful in your design. Variegated shrubs are beautiful year-round. Variegated rockrose (Cistus x hybridus, “Mickie’”), has bright yellow leaves with lime green centers all year round and large white flowers in summer. Holly leaf Osmanthus (Osmanthus heterophyllus, “Variegatus”) is so well behaved. It leads a quiet and orderly life while displaying its variegated leaves of white with green centers. It does like a bit a shade in the afternoon, but other than that it does not ask for much.
Ornamental grasses that stay green and keep their pom-pom shape year-round can add structural shape to a garden too. A fun one is Lomandra (Lomandra longifolia, “Breeze”). One might even think of some succulents as evergreens. They have some very interesting shapes and textures that can bring an eye-catching element to any garden. Examples are Datil Yucca (Yucca baccata, “Datil”) or the variegated Yucca (Yucca filamentosa, “Golden Sword”).
As luck would have it, every one of these examples of evergreen trees, shrubs and ornamental grasses can be seen in the Sherwood Demonstration Garden at 6699 Campus Drive in Placerville, located behind the Folsom Lake College – El Dorado Center. The 16 themed gardens have many other examples of evergreens along with other trees, shrubs, flowers, ornamental grasses and succulents you may want to include in your own garden design. The Master Gardners are just transitioning from winter hours to our warm weather hours. The garden is now open 9 a.m. to noon Fridays and Saturdays.
