I have a dilemma and am somewhat new to garden design, maybe some of you can help me with suggestions? The east end of our property borders our neighbor's yard and they have an unsightly carport. When we moved in 2 years ago there was no foliage there whatsoever and our 2 lawns butted against each other with a cement curb in between.

I did the only thing I could do at the time and planted 4 japanese privets in a 15-gall size in a row. Since then, they have grown nicely, but I have gaps on either end and they are not nearly tall enough (see photo). I want to supplement the row and am thinking of a few compact trees spaced out to fill the heighth a bit. I like crape myrtles but wanted evergreens.

What would look nice and grow reasonably fast so as to fill in this area? Also, I should mention that I'm not terribly fond of really structured and formal shrubs, but prefer a bit more natural look. Any suggestions would be welcome. Thanks.
