About Thuja ‘Green Giant’ (Green Giant Western Arborvitae)
Prized for its interesting foliage, Thuja ‘Green Giant’ is as attractive as it is versatile. Reaching an average mature landscape size of 50-60 feet tall by a 12-20 foot spread, this specimen grows quickly reaching 20 feet tall within its first decade. The tree forms a uniform, conical habit with flat, deep-green sprays of foliage that resemble layered, splayed fans. Its texture is notably dense yet feathery, offering a refined appearance that sets it apart from other coniferous shrubs and trees with similar form.
Origins And Landscape Adaptability
Introduced into the United States in the 1970-1980s, Green Giant originates from Denmark and is actually a hybrid of Thuja standishii and Thuja plicata. Its continued popularity is due to how quickly it grows, its resistance to diseases and hardiness to temperatures as low as -25 degrees and as high as 100 degrees Fahrenheit. After one to two years, this variety has also been shown to tolerate mild drought conditions.
Care And Planting Instructions
Plant Thuja ‘Green Giant’ in an area that receives full sun exposure using well draining soil. If planting in multiples be sure to leave at least 5-10 feet between each plant to allow space for growth. Water regularly after planting to help it establish well to its new location, then reduce frequency to only when the soil has dried out.
Landscape Design Ideas
Due to its vigorous growth and dependable structure, Thuja ‘Green Giant’ serves a wide range of landscape functions. It is ideal for use as a privacy screen, windbreak, or stand-alone specimen tree. Its ability to create a tall, evergreen barrier in a relatively short timeframe makes it particularly valuable for buffering property lines or softening views in both residential and commercial settings.
