The answer to most of your questions really comes down to what your aesthetic preferences are. The size of shrub you prefer is also a factor.
Some to consider include boxwoods, various dwarf hollies, fringe flower and abelia.
The following web site will allow you to search for Monrovia plants by name, by category (such as "shrubs" or "evergreen shrubs") and by zone (your zone is 7).
When a list of options is returned via the search, you can click on a plant to learn more about it and in many cases to see a photo too.
This way you can see and pick the options that most appeal to you.
Thanks for the question. Please stop in again soon!
