Thank u so much for the advice. That's what I was thinking on the Canna Lily. But still needed the advice from some else. Yes I have a large pot of Canna in my pond right now. I have never overwinter them before in water. But someone said they would be fine left in. Whew, thank you for your help. Oh yeah almost forgot to ask, do the Calla lily need to be I a pottery type pot or is a plastic big one ok? I have used up all my pots and I just had to buy some plastic ones at lowes this week.
