Colorado gardens sit in the Mountain West — a landscape of Rocky Mountain foothills, sagebrush steppe, and montane meadow. The plants below evolved with that climate (semi-arid, cold winters, high sun) and are hardy through zones 3–6, so once established they shrug off the local weather without fuss, fertilizer, or much water.
