White Cedar, also called Eastern Arborvitae, is an extremely common evergreen tree or shrub used often as a specimen, in hedges or for privacy. The name “arborvitae” means “tree of life,” because Native Americans reportedly used the tree for medicinal purposes. The small cones open up to look like small flowers and appeal to birds. In the forest, the tree can grow up to 50 feet high, but it rarely is that tall in cultivation. There are many cultivars that vary in height and other characteristics.
