It is a popular choice for privacy screens and windbreaks in landscaping. It is a highly advantageous and versatile evergreen tree widely used in landscaping. Belonging to the Cupressaceae family, this tree offers many benefits, making it an excellent choice for various outdoor spaces.
Green Giant Arborvitae gets its name from its vast size. They can expand as towering as 60 feet with a diameter of 18 or more feet. These massive trees are part of the Cupressaceae or cypress family. Their scientific name is Thuja standishii x plicata. Although, that's often shorted to just the Thuja. This evergreen started in 1967 when a single tree made its way to the U.S. National Arboretum from Denmark. Recognizing the positive landscaping qualities of this evergreen, propagations were sent out. Today, it's known for its ability to adapt to numerous climates.
The Thuja standishii x plicata is a hybrid tree. It was created in Denmark in 1937, using the Thuja Plicate or Western Red Cedar and the Thuja Standishii or Japanese type. While it was being sent out from the U.S. National Arboretum, The massive evergreen was confused with the T. Occidentalis Giganteoides. Luckily, three botanists from the New York Botanic Garden, USNA, and Holden Arboretum uncovered the tree's true roots. Once its true roots were known, it was given its current name to delineate it from other similar evergreen trees.
The Thuja standishii x plicata has a fast growth rate of three to five feet per year. At thirty years old, it averages 30 feet in height and can continue to grow up to 60 feet. It's characterized by its cone shape and the uniform appearance of its foliage.

Plant Reproduction
Sugar Green Giant Arborvitae reproduces by seeds or rooted cuttings.
Plant bare root trees during the dormant season in early spring or late fall (November through April). Dig the hole twice as wide as the roots so the soil is well-drained. Position the tree so the root flare is at or just above ground level. Fill the hole back with the soil you dug from and water. Maintain soil moisture, especially in the tree's early years, by providing deep, regular watering. Apply a 2-4 inch mulch away from the trunk at the base to retain moisture and suppress weeds. Prune trees during the first few seasons to establish strength and resilience, remove damaged branches, and continue maintenance pruning as the tree matures. Regularly inspect for pests and diseases and apply integrated pest management practices. Protect young trees from mechanical damage and extreme temperatures with tree guards, and stake them if necessary for support, removing the stakes after one or two years.
