Tribie - assume you mean lawn grass and not ornamental grasses.
You mention that you use Crab Grass which confuses me a touch, which, as far as I knew, is a type of grass that people are always trying to remove from their lawns, with the abundant use of the many chemicals manufactured for this purpose.
Am not sure where you live, in terms of climate, am guessing maybe somewhere with hot summers. If you are looking for something that can survive baking hot summers, can't think of the names at present, but know there are a few grasses available especially for this purpose, one of which has to be planted, by someone with a great deal of patience and time on their hands, as each blade has to be planted individually.
There is of course an easy care alternative - artificial grass. Quite a few people use this where I live, and some people find artificial grass very acceptable - but have to say, I think it looks absolutely horrible and plastic grass is not something that I could ever find attractive to look at.
Headfullofbees - love the Dracula Grass, now that to me is, very attractive, although a little unusual for a lawn
