We have zoysia grass and I love it BUT it is very invasive grass. It runs above the ground and below. It has to be dug from flower beds, roundup or similar weed/grass killers will only kill what they touch so the runners under soil have to be dug out. It is alot of work but feels so good under bare feet.
We have inground pool, so I don't know if the invasive nature will be a problem or not.
