Purchased a few discounted Canna Lily. Brought them home, repotted, fertilized, water and sun .... Looking good I think!

I live little north of Atlanta, Ga in zone 7b. Can these survive in my pots over the winter? Any information like variety and ways to propagate. Thanks!!

You are in the minimum growing range for Canna Lilies (Zone 7 - 10). Plants in pots are more exposed to the elements than plants in the ground - a good rule of thumb is to subtract a zone for potted plants so the Cannas would have to be hardy to Zone 6a. If you could place them against a warm wall in a protected location, they might be okay.

I have never gotten a Canna to survive the winter in the ground in my area.

Yes, if you can move them into a protected area that doesn't freeze/thaw you can probably keep them over the winter. When the foliage all dies back, let them dry out a bit, then move them into your basement, or an unheated room in your house, maybe. An attached garage might or might not be warm enough on a really cold night.

My daughter in Salt Lake City (zone 6) keeps cannas in pots over the winter there, on a top shelf in their attached garage. She only loses a few if they get dried out too much, so a tiny bit of water over the winter is needed so that the rhizomes don't wither.
