Giant Stands Tall Among Evergreens
Green Giant is a vigorously growing, pyramidal evergreen
with rich green color. The genus is more commonly referred to
as arborvitae, which is known for its lustrous dark green leaves
in summer with a bit of bronzing in winter months. Green
Giant has the added feature of a faint white streak on the
bottoms of leaves, giving the entire tree a slight but noticeable
accent of color.
This cultivar has been available in the U.S. for 30 years, having
been imported from Denmark. While Green Giant is not
a big seller for North Carolina nurseries, it is gaining in popularity
as an excellent substitute for Leyland cypress. Many lower growing
cultivars also are available and make good landscape additions.
Mature specimens can grow to 40 tall with an 8 spread
so be sure to give them plenty of room. Green Giant
is best used in multiple plantings to create a living frame for
your landscape, lending a feeling of formality to the garden.
The frame also may function as a screen to create more privacy
when planted in rows. If not a frame, then Green Giant
is also effective as a single specimen that functions as an evergreen
Green Giant, as well as most of its relatives, is
not troubled by any significant insect pest or disease problems.
It tolerates a wide range of soil types and hardiness zones. Because
of its popularity in the Pacific Northwest, few gardeners realize
that it has great potential for landscape use in North Carolina.
Growth rates of 2- to 4-feet per year have been reported at the
JC Raulston Arboretum (JCRA) in Raleigh, making Green Giant
a plant with many favorable characteristics.
