There are really no turf-quality native grasses that are attractive in home lawns.  Bermudagrass (not native to the US) is great and much more drought tolerant, insect resistant and disease resistant than St. Augustine.  Next best is Centipede, however Centipede is quite expensive to start. Thrid would be Carpetgrass.  Carpetgrass has a wide blade and most will say it looks like shag carpet of the 1960's.
