46+ Green Giant Arborvitae Spacing. Arborvitae are perfect for your area. So you get a very tall plant without taking up a lot of space.
Thuja green giant arborvitae (standishii x plicata) has replaced leyland cypress as the landscaper's plant of choice for an evergreen hedge or specimen tree. Though many evergreen trees vary widely, the thuja green giant is an arborvitae that naturally grows in a consistent columnar shape, taking very little space but providing maximum privacy. If space and budget allow, two staggered rows.
This is an exceptional landscape tree for use as a screen.
The thuja 'green giant' is a hybrid cross between thuja plicata and thuja standishii arborvitae. Commonly used for privacy hedges, these will typically grow 3 to 5 feet the columnar and upright habit does not require pruning. These two plants demonstrate that even when planted a mere ten feet apart, plants can grow quite differently. Plant several baby giant arborvitaes in a row to create a privacy screen or windscreen that stills let the sunlight into your backyard.
