If you are considering changing the landscape in your yard, have you considered using xeriscape?
Xeriscape is a term coined in the early 1980s by combining “landscape with the Greek word “xeros” which means dry. Xeriscaping seeks to provide beautiful, interesting landscape alternatives by using plants that thrive in Colorado’s semi-arid climate. Xeriscaping is also scalable. You can easily start with a flowerbed of other small space to get the right mix of plants for you.
Denver Water, one of the pioneers of xeriscape, offers a wide range of free resources from plant guides to planning tools. Visit http://www.denverwater.org/Conservation/Xeriscape/ to learn more.
