The superb, low-maintenance Thuja Green Giant Arborvitae can be used for a variety of purposes in the landscape. Since 1965, when it was first delivered from Denmark to the American National Arboretum, it has become a favorite among homeowners and landscapers. With characteristics that outperform both of its parents, Green Giant is a hybrid of Thuja plicata (Western Red cedar) and Thuja standishii (Japanese Arborvitae).
