Okay I'm back and it works really fast.
Here they are.
And more on the way I have three sweet potatoes going.
To answer your question yes you can keep starting sweet potato plants from the vines.
Any place they hit the soil they take root or you can cut the and replant in moist soil.
Once a person gets these things going there is no reason to have to ever buy them again.
Where I live if you leave some potatoes in the ground they will keep coming back.
These potato/plants have been out in the cold all winter.
