A low-impact development garden at the Water Reuse Demonstration Site in Sequim, Wash., seeks to educate people about sustainable landscaping. The garden features more than 2,200 drought-tolerant plants, as well as a rain garden and permeable asphalt. It is expected to have grass and weeds in early stages, but ground-cover plants and mulch will soon crowd them out, says Joe Holtrop, manager of the Clallam Conservation District.
