Arborvitae 'Green Giant'
The 'Green Giant' arborvitae is a large, vigorous, fast growing evergreen. It's natural pyramidal to conical form boasts dense, rich green foliage that darkens or bronzes only a little in the winter. This is an exceptional landscape tree for use as a screen, hedge, windbreak, or single specimen. It is tolerant of a wide variety of soils, but prefers moist, well drained soil, sun to partial shade. It is wind resistant once established and withstands heavy ice or snow loads. Under good growing conditions, it can grow up to 3' a year to a height of 50'-60' with a 12'-20' spread.
‘Green Giant’ is a fast-growing arborvitae hybrid cultivar (T. plicata x T. standishii) that is often promoted as a disease-free substitute for Leland cypress, particularly in the southeastern U.S. Trees may grow to 40-60’ tall with a dense, narrow, pyramidal habit, but can be easily kept more compact by pruning for screens or hedges. In the proper environment, trees can add up to 3-4’ of growth per year. Horizontal to slightly upright branching with sprays of scale-like dark green foliage. Foliage does not yellow in winter. Small, upright, light brown seed cones (to 1/2” long).
Best grown in moist, fertile, well-drained soils in full sun to part shade. Tolerates somewhat wide range of soils and some dry conditions. Best in full sun, but generally appreciates some light afternoon shade in hot summer climates.
