have you considered buffalo grass?

Thanks for your reply. Yes, I have looked into it. I think it requires a sunny spot. The areas I have in mind are tree shaded (which is why turf grass does not grow well). So, I was looking into grass substitutes or ground covers. I love the way some of the alternative no mow lawns look, a little like an ocean of grass. However, because of the lack of sunlight, Mondo was the only thing I thought might grow well there.
