St Augustine grass is soft and has long strand great to go bare foot on, Centipede and Zoya grass is most common in Florida it is what they call a runner grass and it is gross and crunch when you walk on it. At the world I have seen all 3 kinds. If it looks fake it could be St Augustine. If it is really green and plastic looking it probably is. I will be there in Oct. 1st stay here, But I will be checking out the grass.
