Yes, they will sprout new growth with warmth and light. If you have a spot in morning sun to plant them IN THE GROUND, they will do better. You can dig and bring them in this fall if you want.

I overwintered one of mine last year. I cut it right back and in the late Winter it started to show new growth. Unfortunately all the new growth has died off,does that mean it is a goner?

Kay, thank you for your help. i agree that plants do better in the ground, but renting I have found it better not to put anything in the ground, maybe someday. I do have a question about wintering the tubers after they are dug up. Do you treat them like dahlias? What do you store them in and do you keep them just moist? Thank you.
Thistle, I am not sure about your Snail Vine, if it had new growth and then had a frost or freeze, it might have got the tops and hopefully it is ok. I have found they do not like to be in wet soil and that they will rot if too wet. I hope yours makes it. I have only 1 tuber out of 3 or 4 that is growing. I do have them in well draining soil in the house and am keeping just moist hoping they grow.

Karan, I winter them in the same pot in which they grew - just cut them back and leave them alone. They go in my heated/cool basement in Oct. and I only lightly water them once a month. They continue to put out new growth all winter because I have them in a picture window, but not enough to matter. They go outside in the first week of April.

Thistle, cut off the wilted vines and let it go almost dry. It will put out new growth when it has been in the fresh, humid and warm air for awhile. Don't give up on it. Most people don't realize that plants grow in cycles, which is nature's way with all growing things. Let it rest and let mother nature do her thing.

Update on my snail vine, NOT GOOD ! Unfortunately the new growth of my vine died off and upon further investigation the tuber had turned soft and very mushy,Thank goodness I had started some seeds and will still be able to have this wonderful fragrant vine once again this Summer.
