One of the highest quality evergreens available! Green Giant was introduced to the gardening public by the U.S. National Arboretum. And what an introduction! This outstanding variety is a vigorous grower often growing over 3′ per year. Very adaptable trees grow in almost any soil conditions whether you have sandy loam or heavy clay. Trees are extremely uniform in pyramidal shape and require no trimming. Green Giant is very tolerant to pests, diseases and drought. Eventually reaches a height of 60′ tall with a base measuring between 12 and 20′. This tree is beautiful when grown as a specimen tree or as an evergreen windbreak. Plant 5 to 6′ apart for a really fast privacy screen, otherwise 10-12′ apart. Green Giant can be trimmed to any height and width. Prefers full to partial sun.
