Answer: Thank you for asking. This Q&A service is intended to assist homeowners with their home gardening questions. Since you are a professional, I would suggest you develop working relationships with some of your local professionally trained nurserymen and also with your local county extension personnel. They should be able to help you analyze the growing conditions at a specific site and help determine which plants might thrive there, then you could select the most appropriate for your design from among those. You might also consider training as a master gardener, the Maricopa County class is forming now according to their web site. Here is the link, it should also lead you to the local extension office. You may need to cut and paste the complete url to make it work correctly in your browser.
Best of luck with all your projects!
