The gov't redid a sidewalk by my house and threw a couple pieces of sod down with this kind of grass. It looks similar to what they use in some of the medians. I want to find out what this is because they laid it down in some sand, without water, and without fertilizer, and it is growing like a wild fire. My yard is almost completely sand and we have struggled to really get anything to grow in it, but this has really taken off.
The first picture is what they put down and the second is where it has spread to. There is a little St Augustine, but I am looking at the thinner blades. I'm thinking Bermuda, but any confirmation would be great.
