Designing a garden for the Denver/Boulder area involves considerations not found elsewhere. In the words of Tom Altgelt, a premier landscape architect on the Front Range of Colorado, “Every region for which I have designed landscapes has its own unique character, with special challenges, opportunities, and needs. In the Denver/Boulder front range area of Colorado, the biggest challenge is the climate.” We have to deal with winter weather, alternating with mild days, for just about half the year.
