Park Hill Tree Lawn Reno We reduced the grass in the tree lawn by 50% to cut down on water use and maintenance. On the south side tree lawn, we used exclusively drought & heat tolerant plants like Manzanita Panchito, Yucca, Hyssop and Ornamental Grasses. The installation was done by Big Dreams Landscape Services, a local Denver company. The blooms in the foreground are Red Creeping Phlox, they are a great drought tolerant, evergreen plant that blooms April and May. Before Photo Related
