Description:

Green Giant Arborvitae are a fast-growing, upright, pyramidal evergreen. They are perfect for privacy or wind screening; very resilient and resists ice and snow damage, grows in almost any soil type. For dense privacy screens, space them 4-6' apart.

Ornamental Features

Green Giant Arborvitae is primarily valued in the landscape for its distinctively pyramidal habit of growth. It has rich green evergreen foliage. The scale-like sprays of foliage remain green throughout the winter. The shaggy brown bark adds an interesting dimension to the landscape.

Landscape Attributes

Green Giant Arborvitae is a dense multi-stemmed evergreen tree with a distinctive and refined pyramidal form. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

This is a relatively low maintenance tree. When pruning is necessary, it is recommended to only trim back the new growth of the current season, other than to remove any dieback. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

Green Giant Arborvitae is recommended for the following landscape applications;

  • Vertical Accent
  • Hedges/Screening

Planting & Growing

Green Giant Arborvitae will grow to be about 20 feet tall at maturity, with a spread of 8 feet. It has a low canopy, and should not be planted underneath power lines. It grows at a fast rate, and under ideal conditions can be expected to live for 50 years or more.

This tree does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid.
