I have 3 of these trees on the side of my front yard, and I don't know what they are! We moved here 2 years ago. I have kept them pruned as they are - I like how they look (I know I need to get the little shoots at the bottoms). Last spring/early summer, they flowered a bit - I actually thought it was just new leaves, but it didn't happen this year so I'm guessing it was small flowers. I am assuming that I pruned too late in the fall/winter, and that is why they didn't bloom this year. I wish I had more info on them, but I don't know how old they are or how long they have been here. I like them, but I want to learn more about them so I can do right by them! I'm in zone 7 - Western SC.
Thanks for any help!
Here is a close up of the leaves:
