I grew up in the SE US and we had Bermuda grass mostly but St Augustine in the shade and sometimes Zoysia grass if you were rich and in the pastures (flying field) it was Bahia. The pear cactus was very prominent in the coastal plains pastures but not in the piedmont areas

Here in the north we have Bluegrass and the various fescues (flying field) and sometimes perennial Rye grass

I was just amazed that there was any grass at all in that area.

Your vegetation looks nice

Maybe not so much sand in your carb?
