I think these are all great suggestions and I would just like to add that I grow a Nandina, 'Heavenly Bamboo' that gets 8 feet tall but you can prune it any size you want, it has beautiful neon red berries and year round interest, and other evergreen shrubs like 'Golden Mop', 'Emerald Green' arborvitae which is the only one you can prune, also I love my Camellia Bush.
The one Bob suggested is something my mother had and I never knew what it was she just called it the
'Speckled Bush', but I do know it grew fast because I was always pruning it!
