Thuja occidentalis 'Smaragd' - Emerald Arborvitae

The 'Smaragd' cultivar of the common arborvitae is a popular compact version of some of the old school pyramidal arborvitaes that grew too large and fell apart in the snow. Growing more conical than columnar, they make a nice hedge growing to about 12' by 5' at the base. Dark green for the most part. I was under the impression this cultivar was a hybrid, but I cant seem to find that reference any longer. The foliage resembles foliage in the oriental arborvitae group. 


Foliage is scale-like, in pairs, along an almost oval stem. Leaves tightly clasping the stem and not diverging at the tip like some others. New foliage is light green, older foliage is emerald green, which is the american name for this cultivar.



Branchlets are flattened, somewhat fan shaped and held partially vertical.


This plant is often called 'Emerald' Arborvitae in the USA, we can't pronounce foreign words very well…..

Misidentification:
Other arborvitaes that form columns. Look for the smaller size plant, nice color foliage, and the slightly vertical orientation of the branchlets.
