Has anyone had any luck growing one in a pot? I have read loads on them and have always wanted one. Most advice has said to take into green house over winter (which we don't have). I have also read that they can be cut back and wrapped for the winter outside. Anyone done this? We live in the southwest so quite mild but we do get frost. It will be in a south facing courtyard near the house, so plenty of sun in the summer. I just love the look of the big leaves.
