I haven't tried it, but I would think it would work just fine, assuming you mean that you are going to cut off and plant green shoots from the overwintered plant. I've done it with ornamental sweet potatoes, keeping them alive and growing inside all winter and then cutting off cuttings and either planting them directly in the ground or rooting them in water for a few days and then transferring them into the ground. Both methods gave perfectly wonderful results. Edible sweet potatoes shouldn't behave any differently from ornamental ones.

I am growing some of the heirloom edible sweet potatoes I got from Gary in 2010. They are growing in containers in a sunny corner of the weight room. If I can keep them alive through this winter, I'll plant cuttings from them in the spring.

Thanks Dawn. When we had the seed swap last winter George sent 2 or 3 tiny sweet potatoes. I saved one and sent the other out in someones package. I tried to get it to root in water and it just barely made little leaf buds. I put it in a container of soil in the window and it is now about 6 inches tall and bushy. I started another kind today and I will see if I can keep them growing through the winter.

Carol, I took the top of a sweet potato and placed in potting soil around the holidays ( Christmas or Thanks giving) and placed it in a plastic rain gutter I have rigged up to go across the kitchen window. It grew and pretty well filled the rain gutter, which is about 26" long. I pulled the root ball apart and planted a 22' row in the garden. That was the first group of potatoes I harvested, which filled a 5.5 cu. ft. wagon.

The end of the sweet potato was already starting to sprout, but the window was a little too cold for it until warmer weather came. At that time I had to tie strings across the window to support the runners. I also had to water it often because it had such a small rooting area.

I plan on trying the same thing this year. I have some ornamentals rooting in the bath room now.

I am glad that I asked this question, because I had tried to save ornamental tubers in the past and failed. I never thought of trying to root them and keep them growing over the winter. That sounds much easier.

My house is small and I don't really have a good window to grow things in since we seem to have wall-to-wall stuff. If I can keep it going inside the house until I start my Spring seeds, I can move them under lights at that time. The first one seems to be perfectly happy in the kitchen window for now.

I had cut some basil and brought it inside and had it in a glass in the window. It stayed healthy and I have continued using it for a couple of weeks. Yesterday I noticed that it had all rooted. Today I dug out the potting soil and potted it up. Soon I will have a window full. LOL

Carol, here is a picture of my ornamentals I am rooting. I have never tried this before either, but I have never had any ornamentals that bloom this well, and did not know if I could find some like this next year.

Its still a long time till spring.
