This beautifully variegated grass of white and green sure looks good at first. But if left unchecked will spread all the way across your garden into your neighbors and throughout the neighborhood. Ok maybe not that bad. If you must have it put it somewhere it will stay contained. If you wanna get rid of it, keep on diggin. You can have it gone in about 2-3 years, but stay on top of it, or it will creep back into your life.
