Certain evergreens are trees and shrubs that remain green year-round. The term includes fir, yew, and shortleaf pines. Fir is a coniferous tree with needle-like leaves and cones. Yews are evergreen shrubs or small trees with flat, dark green needles and red berries. Shortleaf pines are tall evergreen trees with short needles and cones. All of these plants are popular for landscaping and provide a variety of benefits, such as providing shade and shelter, reducing noise pollution, and improving air quality.
