What we call tickle grass is a lot finer and only grows about 6 inches tall. Until I figured that it looked taller then that I had thought tickle grass also. That's why I said to slide your hand on it. If it's greasy feeling it;s grease grass if it isn;t it probably is real healthy/robust tickle grass.M.Magis":33h7qmbb said:Grease grass was my first thought as well.
