I'm here to ask the experts. I live in N. Georgia on a hillside lot and want to create a border of shrubs around the front edge of my lawn to screen off some of the traffic noise from the road about 50 yards downhill. The area to cover would be about 150' so I'd have to plant quite a few and so would want to start with 1-3 gal plants rather than more mature specimens. Because of the way the angle is down to the road, they don't have to be more than about 4' tall to serve that function, but could get up to 10' or so before blocking my view or getting out of proportion. Color from blooms or foliage would be a plus. I prefer dark green to varigated though if it's not a blooming plant. Sun is mostly full sun, but there is a high tree canopy that puts the area in the shade in the morning. So far I've come up with Privets as the obvious choice. Any other ideas?
