Evergreens have gotten a bad name because they were over used as foundation plantings and as they outgrew their intended space were sheared into submission.
Evergreens are useful in landscape design as vertical and spreading elements. They can even be specimen plants in a design. The key is to incorporate trees, shrubs and perennials with the evergreens so that they are not the focal point during the growing season.
In winter, evergreens add color in an otherwise drab color palette. They become the stars of the landscaping and the deciduous trees, shrubs and grasses move to supporting roles.
Consider including a few evergreens in your landscape. Select plants that will stay within their intended space and you will enjoy the green in winter.
