Green Giant Arborvitae
Thuja standishii × plicata 'Green Giant'
Fast growth and maximum height for full-property privacy
Green Giant arborvitae (Thuja standishii × plicata 'Green Giant') is the heavyweight of privacy evergreens. A vigorous hybrid that puts on roughly 24–36 inches of height a year, it's the fastest route to a tall, dense screen, perfect when you need to block a two-story view, buffer road noise, or shelter a large property from wind.
Reaching 25–30 feet or more with a 5–7 foot spread, Green Giant needs room to perform. Spaced 4–5 feet apart, a row matures into a towering living wall far taller than any fence, and it shrugs off the winter burn, bagworms, and deer browsing that trouble more delicate evergreens.

- Fast Growing
Best For
- Large lots and acreage that need a tall, fast-growing screen
- Blocking second-story windows and elevated sightlines
- Windbreaks and road-noise buffers along open property edges
- Areas with deer pressure, thanks to its better browse resistance
Planting & Care in Michigan
- Space 4–5 ft. on center; Green Giant grows wide as well as tall.
- Give roots room: keep the row at least 4–5 ft. off a fence line or hard structure to allow for mature spread.
- Water deeply and consistently the first year: about 1 in. or 10 gallons per week, split over 2–3 waterings. Its fast growth depends on steady moisture while it establishes.
- Little pruning is needed for screening, but a light annual trim keeps the form tidy and encourages density.
Green Giant Arborvitae FAQs
How fast do Green Giant arborvitae grow?
Once established, Green Giants commonly put on 24–36 inches of height per year, among the fastest of any privacy evergreen. Starting with our larger 6–9 ft. stock gives you a meaningful screen almost immediately.
How far apart should Green Giant arborvitae be spaced?
Four to five feet on center. They grow tall and wide, so tighter spacing leads to crowding and poor air circulation. Proper spacing still produces a fully solid screen at maturity.
How big do Green Giant arborvitae get?
In Michigan they typically reach 25–30 feet or more, with a 5–7 foot spread. That scale makes them ideal for large properties, but too big for tight suburban lots, where Emerald Green or American Pillar fit better.
