Are you a new gardener? Do you find it difficult to keep the names of all those perennials, etc. straight? Here's a tip to help you learn them. It involves visiting a garden center such as the one in this picture: http://landscaping.about.com/od/perennialflowers/qt/perennial_types.htm
This is cool! Backyard Landscape Ideas. Check the buttons that apply to your yard and BHG creates a guide that fits your criteria and you download it onto your computer. It's really, really neat for those who aren't quite sure what to do with their garden/yard, wants to get more ideas, or even see if what you've come with will work for your yard!
