Choosing Trees behind rhodies
I'm new to this site so foregive me in an advance if I should blunder on my post. I live in a 1920s cottage on a wooded slope in Zone 7. I need to install a 6 to 8 ft. fence for privacy from one neighbor. I have a 30'x 30'x 30' triangular peice of land that will be framed by this fence and the steps leading down to our house. I just purchased 3 Verigated Ponticum Rhododendrons for the center of the bed but would like to put trees or large shrubs against the fence as a backdrop. The area gets about 3 hours of sun in the early morning and then some dappled shade but a lot of full shade. The shade is caused by very, very high trees in this wooded enclave of homes. Any ideas for what to put up against the fence as the background for the Rhodies? I would like something 8-12', somewhat narrow. Thanks for your help.
