I have a couple of persian lilacs and a dynamite crepe myrtle, and a white hydrangea. I was going to use some golden vicary but someone told me theirs had pretty intensive roots that choked out surrounding stuff. So I tossed that idea. Wondering about nine bark? or a baby's breath spirea? Maybe some type of weigala. I need about 80 ft length filled in. I am doing this hoping to help deter deer, later I will add a 6 ft chainlink.
