mine is penned in for that very reason, when I first put it out there is was swaying this way and that. I weighted it down with a heavy pot with a plegonium in it. Its one I forgot to bring in over winter and I was suprised through the snow it still had green leaves on it, I felt guilty about leavig it out in the cold and thought I know I'll put it in the growhouse to warm it up a bit, and now it looks dead. go figure.
