Its a very important step to Learn about the care and uses of landscape plants, including the trees and shrubs involved with your landscaping project. Some landscape plants have a practical function. One example of a practial function of a landcaping plant is the groundcovers on hillsides which help to prevent soil erosion, shrubs in a foundation planting can reduce your heating bill, and trees can serve as windbreaks or aids to block or control direct sun exposure in your kitchen or bay windows. But in all these cases, aesthetics, as well as functionality,shouldl be considered. Other plants, of course, will be grown mainly for their beauty, whether singly (specimens) or in groups (flower beds, hedges).
