The holly, just like in the Christmas carol. No ivy here, though. I can’t stand the stuff; it doesn’t know when to stop trying to cover everything in its path. Do you have a tree? Ivy will happily swarm up the trunk and smother the branches. What about a house? Not a problem – ivy will get to work on turning it into a green hill, if you don’t fight back.
Ivy. Bah, humbug.
