Answer: There is a program called "Planix Photo Landscape" where you can scan in an image of your property, then play around with different plantings. The program is manufactured by Softdesk; ph# 816-891-1040. I can't vouch for how useful this is, however.
There are lots of great gardening books with photos of popular landscape plants. A trip to your local library or bookstore is sure to land you some good ones! You may even find some particularly useful regional guides.
