Canna lilies are tall flowering plants. Ours happen to be red. I got them from my mother-in-law. Some of them grow taller than I am. They can be quite a showy plant.
The bulbs must be brought inside each fall. There are some that survive the winter, but It is most reliable for their well-being to bring the roots indoors for the winter. I dig them out, chop off the stem of the plant and discard it. The roots get carried to the south side of the house. If the weather permits they will lie out there in the sun for a few days to dry. If not dried, they can mold and that will harm the roots.
I keep the roots stored all winter. Some bulbs will shrivel up in the safety of the cellar. In the spring, I toss out the ones that have shriveled up or look unhealthy. I plant the best of the rest. If I am particularly lucky, I will have enough bulbs to give to a friend.
Yes, the Cannas are in. That is one more job finished as we look forward to the coming of winter.
