If you can help her get it started, then she could grow some of the wheatgrasses that will grow in AR. These are full sun, prairie type grasses which look great (see below) when sowed fairly dense and mowed once a month. They require very little water beyond rain and little to no fertilizer. There are many varieties of wheatgrass and some will not thrive in AR.

Here is a picture of bpgreen's lawn in Salt Lake City. It is a mix of wheatgrasses, blue grama, and strawberry clover.

He doesn't start watering until about June and then only waters about 4 times throughout the season. Mowing is monthly to keep the seed stalks down.

Thanks. I will pass that to her as an option. A neighbor just cut hay and it has the seed stalks in it. It is a mix of fescue, bahia, and bermuda. We were thinking of putting an inch layer of this hay down and just let it self germinate next spring. If we were to mix wheat grass seed in this, would you put the seed ontop of the hay or under it?
She has no care of what type of grass she has, she just wants a lawn so the dogs do not track too much dust and mud into the house.

Underneath if it isn't too much trouble.
