American boxwoods in 36-inch concrete pots serve as a low hedge. Potted boxwoods offer formal elegance with little maintenance. This large American variety creates a living wall in a line of concrete planters.
I like this kind of stacking for the grizzly bear stand. You could layer with different sizes and textures of baskets/pots. Try to keep the feel pretty neutral (baskets, old buckets, etc). And look for different shapes and textures of greenery.
