I love these plants for their giant, tropical look! I've yet to successfully overwinter in the ground, but, last year I dug one up, put it in a giant plastic pot, and then into the basement. Occasionally watered, but mostly ignored. In the spring, it had one green leaf left, and I put it back into the ground. It has doubled in size this year--probably about 6'! I will be trying the same method again this winter.
