Good luck - I hope your sweet potato continues to thrive and send out more shoots. It would be great if you can actually grow your own sweet potatoes from the slips.
I tried it a few years ago but started a bit too late. During the winter I place the pot inside - it was a beautiful plant. It became quite large - so I checked and found many small potatoes. The pot was too small so I abandoned the project. I will try it again this year.
