Becky, I'm pretty sure you have seen pic's of our hedge but I thought this was a good place to post a few.
It is a clipped Hew. We were given small seedlings maybe 12 inches high about 30 years ago. They were planted in a L shape coming out from the side of the house with a break you could walk thru in one side. It has grown into a beautiful tall hedge about 10 ft high 3ft wide.
Here you can see the L shape
Here you can see the arch we have grown thru the hedge. We call it the entrance to the Secret Garden. Of course the secret to the Secret Garden is that there is no garden there just a small side yard that hadn't been developed yet.
