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. .
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.
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.
Linnaeus, the Swedish botanist who assigned the Latin name to this species, picked up on one of the plants more sensory traits. The genus name, Thuja, is from a Greek word for perfume. Squeezing the evergreen leaves releases an aroma that is nothing less than nature's perfume. The specific name, occidentalis, means "west," the direction from Sweden where this tree was discovered.
The native North American tree, America Arborvitae (Thuja occidentalis), was useful in early canoes and medicines and became the first North American tree to be introduced to Europe.
Green Giant arborvitae prefers moist soil. Avoid poorly drained and wet sites.

Small, inconspicuous, male yellowish, female pinkish color
One half inch oblong cones, green in summer, brown in winter.

The benefits of bare-root trees
Our trees are delivered with natural bare roots which have been dipped in hydrating gel prior to shipment to keep the roots moist and healthy. As their abundant, fibrous roots aren't confined by a container, bare-root trees get off to a more vigorous start compared to containerized roots which typically need more time to adjust to transplanting. Bare-root trees typically surpass the size of larger containerized trees in only a few years.
