Questionwhat is the difference between a thuja green giant tree and one called giant arborvitae? I ordered the thuja online, then saw a local nursery have the giant arborvitae? Thank you
AnswerThuja Green Giant is a hybrid cross between Thuja plicata and Thuja Standishii Arborvitae,Thuja standishii x plicata.
Giant arborvitae is Thuja plicata. Common names can be confusing and the same tree is called a different common name in different parts of the world. IF you can always go by the Scientific Name.
