Need 3D Landscape software?

I am looking to design my own backyard landscaping and am looking for software. Either free or worth the price. I want something that I can enter a pic or create a sketch of my own home and landscape around it. Thank you.

Check out Google earth, and the free version of Sketchup they provide. You can get an ariel photo of your place, and then use sketchup to do your design, make sure you check out sketchups design warehouse online, free plants, trees all kinds of stuff
