Thuja Green Giant is the one that gets 40 feet tall, not the Emerald green, this gets 8-12 feet tall. Also I have heard this is the only Arborvitae that doesn't mind pruning. I have two in my corner garden and I do not plan on letting them get 12 feet, I will keep them around 6-8 feet tall. Very beautiful evergreen, easy to care for.

I give this plant a positive because it has survived the last three years in quite shady conditions, along with neglect in the area of watering. I now try harder in the summer. It's all good, though. I planted three as a screen near the road, but there is inadequate room if they get too huge. Then I'll report on attempts with pruning!

Useful as a hedge, on corners, in the background, etc. In my experience, emeralds only get around 4' wide and 12' -15' tall. They grow moderately fast. Stays a nice green all winter here in TN. Problems sometimes occur when placed near a downspout in clay. They don't like to sit in water. Also, in the drought of 2007 here, lots of these died or nearly died. Some that survived have their south facing sides scorched and still remain brown. If it is dry in the summer, make sure to water these. They won't repair the browned/ dead areas. Also watch out for bag-worms. Because of the narrow growth, Emeralds are a very useful plant.
