Coral Reef goes like gangbusters in my 8a sun. It's on a par with creeping Jenny. I walk on it, divide it, excessively water it, let it go dry, it's a maneater! It's in the ground. Lemon Ball is also a good spreader for me. I can't keep a Blue spruce alive for the life of me. Just bought Lime Zinger and John Creech, so the jury is out.
