One of the best trees to plant for privacy is the coniferous Excelsa Cedar (Thuja plicata Excelsa). The Excelsa is the smaller of two species of Thuja plicata.

The Greek word ‘plicata’ means folded in plates, which is in reference to the tree’s leaves. Thuja plicata trees are also referred to as Pacific red cedar.
Thuja plicata trees are members of the genus Thuja L and the cypress family Cupressacaeae. The four other members of the Thuja L genus are Thuja koralensis, Thuja occidentalis, Thuja standishii and Thuja sutchuenensis.

Cherry trees are members of the “rosaceae” (rose) family and ”Prunus” genus, which includes plum, peach and almond trees. Cherry trees include both the commercial fruit-bearing trees (Prunus avium and Prunus cerasus) and ornamental flowering cherry trees, known for their masses of beautiful, fragrant pink or white blossoms. 
Trees can be used as natural screens to create more privacy for you and block unpleasant sights. They can also reduce wind, light and any unwanted noise from cars, commercial properties and outdoor machinery. You can also use trees to define and enhance the look of your outdoor space, improve the view from your home or building, add environmental interest and even change the flow of traffic through the area.
