The green giant arborvitae is a large, vigorous, fast-growing evergreen—shooting up by as much as 3 feet per year until maturity. Its natural pyramidal to conical form boasts dense, rich green foliage that darkens or bronzes slightly in the winter.
This is an exceptional landscape tree for use as a screen, hedge, or single specimen. It is also resistant to wind once established and can withstand heavy ice or snow, making it a good choice for a natural windbreak.
The green giant arborvitae can be expected to grow in Hardiness Zones 5–7.
The green giant arborvitae grows to a height of 50–60' and a spread of 12–20' at maturity.
This tree grows at a fast rate, with height increases of more than 24" per year.
Full sun and partial shade are best for this tree, meaning it prefers a minimum of four hours of direct, unfiltered sunlight each day.
The green giant arborvitae tolerates a wide range of soil textures. Poorly drained and wet sites should be avoided, and it is very salt-sensitive.
