The Green Giant Arborvitae (Thuja standishii × plicata 'Green Giant') is one of the most popular and fast-growing privacy trees available, offered here in a mature 30-gallon container size. At this size, the tree typically stands 6 to 8 feet tall at time of purchase, giving you an immediate privacy screen with no wait.

Green Giant Arborvitae is prized for its vigorous growth rate of 3 to 5 feet per year under ideal conditions, eventually reaching 40 to 60 feet tall and 12 to 18 feet wide at maturity. Its dense, rich emerald-green foliage maintains color year-round, making it an excellent choice for windbreaks, hedgerows, and privacy barriers. The pyramidal form naturally stays neat without heavy pruning.

This tree is hardy in USDA zones 5 through 8 and tolerates a wide range of soil types, including clay. It performs well in full sun to partial shade and is notably resistant to deer browsing, bagworm, and other common arborvitae pests. Once established, it has good drought tolerance. Plant 5 to 6 feet apart for a solid privacy screen, or 8 to 10 feet apart for individual specimen use.
