Denver’s Mile High Gardening Conference brought together gardeners and growing experts from around the world for a two-day conference at the downtown Sheraton Hotel. To celebrate the conference, Urbanarbolism and UnusualGreen designed and installed a 16×20 ft vertical garden at the hotel’s entrance. The living wall acts as both a sign for the Sheraton and an example of how plants can be installed on a vertical surface.
The challenge for this project was to use hardy plants that could handle the hot summers in Denver (when temperatures hit over 100 deg F) as well as the cold winters (when temps dip down near 0 degrees). The hydroponic installation is remotely monitored in Spain by Urbanarbolism and requires almost no maintenance. Just once a year, the plants will be pruned and a water filter changed on the system. You can see a full list of plants included in the installation on Urbanarbolism’s site.
