Shrubs of Substance

Sometimes there is a large, empty area in a garden that needs something substantial to fill it up. For one reason or another, a tree would be out of place. Perennials and ground covers would be too small to provide the required visual oomph. What is needed is one really big shrub to fill the space and bring some interesting form, flower or fragrance into the garden. Here are some possible choices.
