in the GA sandhills, bahaia grass is considered an invasive.
It grows without any supplemental water... even in this drought... Like Fresno, the weather here is usually droughty... and unlike east TX, we're in a rain shadow here...
But.... just because I have patches of bahaia that I don't try to exterminate.... this doesn't mean that I would ever encourage anyone to plant it.
It's paltry looking (right now)... turf doesn't ever look good in the drought...
I do have patches of mondo (lilyturf) (Liriope sp.) that look pretty good without any watering... but the deer are starting to graze it....
So... if you have a bit of shade, maybe experiment with a mondo lawn.
Isn't there anything else that you'd like to grow?
How about a nice patch of delosperma?
You couldn't walk on it, but it would provide a nice ground cover... It's even invasive out there... so maybe check first before planting...
How about a nice patch of Sempervivum?
Anything but water wasting turf, out there in the drought....
You know there are a few people out there that have more money than sense... hauling in truckloads of water for their turf?

Doesn't make sense...
