I have similarly had good results saving them in a bag of dry peat moss in the basement over winter, then potting them up in the spring. I have never cut them into pieces though. Last year, after drying them off and dusting off all the dirt, I wrapped them in Saran wrap until January, then in planted them in pots of dry seed starter mix andkep them in the basement. In spring I wet the mix and brought them into the light and they sprouted. It took longer this way though. I don't think it matters if they're roots or potatoes. I think potatoes are just thickened roots?

Hi Tina: I am interested in your tri-color sweet potato vine as well as your white brugmansia. Do you have a photo of your yellow one? I would like to know what shade of yellow is yours, since there are several. I have many tropicals including: passiflora edulis, heliconia red flowering, giant elephant ears (diferent kinds), gingers white, red, shampoo. others Please check my list. Thanks

linnea, I just posted an answer in the Annuals forum (Home, but in that winter sleep, zzzz...). Basically the same answer you got here. The main thing is keep them dry enough not to rot. I cut the sprouting ones in pieces in the spring and let them dry before potting up, though sometimes they rot anyway. If you have more than one tuber, you might try both ways. If you do, report back! :)

It's true that all sweet potato leaves are "edible"... which only means they won't kill you if you eat them. ;-) Whether they are palatable is another matter. I've tried several varieties of sweet potato leaves as boiled greens, and there were considerable differences in taste. An orange-rooted variety (from the supermarket) had tough leaves. Two ornamental varieties I tried had very unpleasant flavor, almost chemical... about as appetizing as eating pine needles. The shoots sold in Asian stores are the best varieties for leaves. There seem to be several different varieties grown for their leaves. The heavily-cut leaves of "kamote" that I grew in San Diego (from a Filipino store) were different from the more rounded leaves of the variety that I purchased from an Asian market where I live now. I don't know the variety name of either one, but both have white tubers. As for the tubers: I've mentioned previously on this forum that the variety I grow now for leaves - while very good for that purpose - is unsuitable for tubers. When I first dug up the plants at the end of one season, I wondered why there were so few tubers under the plants. Then I noticed that there were several thick roots leading horizontally away from each plant, and dug carefully to follow one. I found a tuber over two feet away, and almost a foot deep!!! The tubers were dry & tasty, but the massive amount of excavation required to find them all made harvest of more than a few impractical. This question has come up quite a few times on this forum, without a definitive answer... but there is a possible solution. You might want to contact Glen Drowns of Sandhill Preservation Center. He is a collector of sweet potato varieties, and offers a huge number of them, both heirloom & commercial. He might be able to steer you to one that suits your needs.
