Sustainable Landscapes Garden Objectives

The Sustainable Landscapes Garden will serve as Tucson's premier destination for sustainable landscape education, designed to inspire and inform both homeowners and landscape professionals. This demonstration garden will showcase practical, research-based landscape techniques adapted to arid environments, feature ADA-compliant paths, bilingual signage (in English and Spanish), and an outdoor classroom that actively harvests rainwater from its roof. The garden will be divided into 18 sub-gardens. It will actively harvest rainwater, utilize berms and swales throughout the landscape, and rely on reclaimed water.
