The Grass Roots outdoor exhibit is a 1.3 acre site at the National Arboretum in Northeast DC (the Arboretum is a 446 acre site in total). We now have a small golf hole, a small natural and artificial athletic field, warm-season agricultural crops, a rain garden planted to grasses, and several ornamental grass beds. By the end of the month, we plan on having permeable pavers installed for additional walkways, and sod for the warm- and cool-season grass displays installed. We plan to include tall fescue, fine fescue, Kentucky bluegrass, and perennial ryegrass as examples of cool-season species and at least zoysia and bermudagrass as warm-season examples.
