Savvy Colorado gardeners already know about the many benefits of converting thirsty lawns into attractive, water saving xeriscapes. The real treat lies in discovering the wonderful variety of plants available to use in xeric gardens. In response to consumer demand, Colorado nurseries are now growing more varieties of drought adapted plants than ever before. The result is a rich tableau of xeric plants, well adapted to Colorado's diverse conditions.
