The two fluffy white Limelight hydrangeas in this photo are not different sizes due to forced perspective. The one in the foreground is more than twice the size of the one in the background. Both shrubs were purchased at the same time from the same store and started out the same size, one on either side of my front door. The smaller shrub is actually in better quality soil than the larger one, which is kind of stranded on a patch of earth between the sidewalk and driveway. The difference? Sunlight! Both face west, but the smaller shrub gets shading from the house, whereas the larger shrub is outside of the shade’s influence, on the corner of the house. It gets full sun from almost all sides. I believe this shows the difference the sun can make to sun-loving shrubs.
