This fast-growing variety is a cross between Japanese cedar (T. standishii) and western red cedar (T. plicata).
With a conical shape and dense green foliage that holds its color well in winter, 'Green Giant' closely resembles western red cedar. However, it grows an amazing 3 to 5 feet a year, especially in warm climates (zones 7 through 9), allowing gardeners to buy and plant small plants and achieve a tall hedge in less time. It eventually can grow to 30 to 50 feet tall if not pruned. 'Green Giant' prefers full sun but will grow in part shade. It requires minimal maintenance, tolerates poor soil, has no major pest problems, and is low on deer's most desired list.

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.
