So-called "no-mow" grasses vary in their regional makeup but often have a fair amount of fescue in them. I'm not sure how well that would do in Atlanta.
maybe Zoisia grass? When I had it in NY, I would only need to mow it about once a month. It does turn brown in the winter and is extremely drought tolerant
Zoysia is suppose to be great for hard-to- cover areas ! "Through heat & drought.Thrives in blistering heat. Zoysia farm Nurseries will ship at the best planting time for you" Sounds good to me! : )
Check out the Mother Earth News Archives. There are several different varieties of 'no-mow' grasses, which, in fact, are ground creeping plants. They're nice, soft, & beautiful when cared for properly. Enjoy.
It does sound like a good idea.
