Or only grow a few inches high and then stop growing.
It’s called ‘dicondra’ or dichondra. I planted it in my uncle’s yard in Encino Hills, LA area way back in the early sixties. You can cut it like grass, but it will not grow into knee-high scrag if not mown regularly.
They HAVE that stuff, I swear.
I accidentally bought a 40-lb bag of it at a True Value store (it was privately bagged, maybe locally or something--not a big corporate product) and it was called Something-something Short Grass.
I put that stuff in to cover the big patch in my front yard where the new septic tank went in, and (again) I swear it never grew past an inch and a half.
You might think that would be fine but the rest of the yard around it continued to stretch toward the heavens...and the short grass stuff never thickened up and would burn and wither in the sunshine no matter how much water I poured to it...
