Now it is late August, and I don't know where they came from but from the 2 I purchased I now have 22 beautiful cannas.

I now have the threat of fall and soon winter and have been trying to figure out what to do with everything. I just can't leave them out there!
Answer: greenhouse in my basement!

Now the questions. Do I have this many cannas because mine seed?,
If they seed should I just find the seeds and bring them in to pot up?
I so much want to bring in a couple of my cannas to pot for my greenhouse (this would be so beautiful). However, will they grow successfully under lights?

I will have some sun light, as the basement door opens on the south side of the house and hubby is putting up a glass enclosure over the basement door like an attached greenhouse with doors to the outside.

I was reading about the dividing of the cannas and I don't understand the cutting of the eyes to divide? Is there a diagram somewhere that shows a plant with the different parts to help?

I know it is a lot to ask, any help would be appreciated.
Thank you,

Your cannas multiplied from the rhizome which is a large root that grows horizontal underground. It sends up new shoots as it spreads. You can save the seeds and start new plants with them, but they multiply so quickly from the rhizome that it is not necessary.

You can start them indoors early and then re-plant them after the last frost. Again, someone who overwinters cannas would be able to tell you better than me how to store them.

When you dig them up and wash them off it will be easy to see how these plants grow and you will have an idea of how to divide them. If you cut the rhizome into larger sections the plants will get off to a better start next year than if you were to cut it into small segments.
