Green giant arborvitae is a large, needled, evergreen conifer tree. This tree is a hybrid cultivar of T. plicata and T. standishii. This hybrid was introduced to the U.S. in 1967 when the National Arboretum received a specimen. Once available to nurseries, homeowners became interested to use this tree in their landscapes. Dark green scale-like needles retain their deep green color through the winter. A mature height ranges from 40-60 feet along with a width of 12-18 feet. This tree can live from 40 to 60 years. It thrives in a moist, full-sun environment with little shade in the afternoon. Ideally, you will find 3-4 feet of growth per year. It is resistant to most diseases, insects, drought, and deer. This tree is not salt tolerant. Minimal landscaping is necessary to keep its shape due to its growth pattern and hardiness.
