With so many areas of the country suffering from drought this summer, we might want to think about ways to conserve water. The average lawn and many gardens use quite a bit of water, but there is no need to do without greenery in our backyards and community gardens. Think about growing plants that require less moisture. Treehugger has a nice slide show on would-be lawns that have been converted into gardens requiring minimum water. The Chicago parkway garden (above) is planted with native and drought tolerant plants that divert rainwater from sewers, provide food and forage for pollinators, and brighten up the neighborhood.
