I had a Canna seedling appear in my garden where I haven't grown any Cannas in years. I dug it up a couple weeks ago after our first frost, but I'm wondering if I should replant it now and try to keep it growing through winter. It seems so small. Does anyone have a recommendation? Likewise, I got some Canna flaccida seeds from the recent BX offering, and wondering if I should sow them now and grow them under lights this winter? Any recommendations? Dennis in Cincinnati
