Green Giant Arborvitae

Attributes:
The 'Green Giant' arborvitae is a large, vigorous, fast growing evergreen. It has a naturally pyramidal to conical form and dense, rich green foliage that darkens or bronzes only a little in the winter. This is an excellent landscape tree for screening views, noise, and wind or as an ornamental specimen. It tolerates a wide variety of soils, but prefers moist, well drained soil, sun to partial shade. It is wind resistant once established, withstands heavy ice or snow loads, has no serious pest or disease problems, and shows better resistance than most arborvitae to browsing by deer. Under good growing conditions, 'Green Giant' can grow up to 3' a year to a height of 50'-60' with a 12'-20' spread. .

Wildlife Value:
Arborvitae provides nesting sites and cover for birds and small animals. The flower buds, seeds, and foliage are a food source, although this cultivar has greater resistance to deer browsing that most arborvitae.

History/Lore/Use:
In 1967, D. T. Poulsen from Kvistgaard, Denmark gave the U.S. National Arboretum a single plant, Thuja standishii x plicata. From this plant, the clone named 'Green Giant ' was propagated. It is public domain tree, so anyone can propagate it from cuttings. The word arborvitae comes the Latin meaning "tree of life". 'Green Giant' arborvitae rapidly became a popular plant and is a good alternative for hemlock in the Northeast and Leland Cypress in the Southeast.
