Mama Bear,
I did a little research and came up with the following alternatives:
St. Augustine, Buffalo Grass, and Centipede Grass appear to be viable alternatives.
These are all warm season grasses like Bermuda grass. However,I should have also asked what country you are in?
I like the following website for variety information, please look at the warm season grasses section!
