The 'Green Giant' Western Arborvitae is commonly planted in the Mid-Atlantic and Midwest of the US. It gets larger than the cultivars of the Eastern or American Arborvitae, not the mother species, and its advantage over the eastern species is that deer don't like to eat the very waxy scaly foliage, while deer love to eat the lower parts around the eastern species.

A large, vigorous, fast-growing evergreen with a natural conical shape. Dense, rich, thick foliage bronzes slightly in the winter. Accepts a wide range of soils but prefers moist, well-drained conditions. Wind resistant once established and can handle heavy ice and snow loads. May grow up to 3 ft. a year under ideal conditions. Can be pruned.
