Green giant arborvitae (Thuja 'Green Giant')
Arborvitae, meaning "tree of life," is a conical evergreen tree with flattened sprays of scale-like leaves. 'Green Giant' arborvitae is a large, low-branching tree with lustrous green foliage. Trees may grow to 40–60 feet tall with a dense, narrow, pyramidal habit, but can be easily kept more compact by pruning for screens or hedges. It features horizontal to slightly upright branching with sprays of scale-like dark green foliage and small, upright, light brown seed cones. Foliage does not yellow in winter. Use this plant in a moist sunny spot alone as a specimen, in groups, or even as a hedge or screen.
