I have half in the landscape and half in huge pots. It is just a whole lot easier, since I have several dozen plants, to bag them up. They just "go to sleep" for 4-5 months. Whether you do what I do or leave them in pots with poor light, they still will go dormant. What I do seems to work. They plump up quickly when potted and put outside in the spring. Believe me, I am no expert here. There are others on this site that are. I just do what works for me in NE Mississippi. It would be soooooooooo nice to live in central-south Florida or S. California and leave them out year-round. Most of us live and grow our plants in non-tropical climates. Ken
