Your solution may be two-fold. First, screen the most prominent portions by planting a hedge. Second, create a focal point in your garden that will draw your eyes and attention away from the portions that are still exposed. Anything can serve as a focal point; a bench, a planting of annual flowers, a bird feeder or bird bath, a fountain or pond. It's surprising how even a small feature drawing your eye can make everything else disappear into the background.
