I want to plant a nice informal hedge in front of my new fence, I'd like something prickly to discourage any kids with spray paint from getting close. I was hoping that there would be enough sun for Rugosa Roses, which do well here, need minimal water, and are pretty and prickly
I've been doing some exposure research and the area gets about 6 hours of dappled sun and 1 hour of full sun per day during the middle of summer.
This picture is of the fence at noon:
If Rugosas won't do well, I was considering Mahonia instead. Any advice?
