Thuja occidentails 'Wintergreen' - aka 'Hetz Wintergreen'
excellent columnar / pyramidal Thuja variety that has a good reputation
for holding decent green color throughout the winter months -
less bronzing / discoloration than several other Thuja varieties. Has
also shown itself to have very good shade tolerance.....along with excellent cold hardiness. Growth rate in
shady locations is somewhat slower that in full sun to part sun
locations, but foliage density is virtually unchanged. Wintergreen
Pyramidal Arborvitae makes an excellent hedge or privacy screen choice
- recommended spacing of about 3-4 feet apart for a good tight hedge or
