This quick-growing tree is often used for hedges or privacy screens and looks incredible in backyards. Leyland cypress (Cupressus × leylandii) typically has attractive blue-green foliage, but some cultivars are more yellow in color, says Abdi. It's susceptible to a wide range of pests, so it may be higher maintenance than other fast-growing evergreens.
