Sweet Potatoes or Yams???

Everyone here in Texas has been planting sweet potato vine for looks in their landscaping. I ran out of seeds for my garden boxes this summer so I took some sprouting sweet potatoes from my pantry and planted them in my grow boxes. My friend Janet Guershenfield is a master gardener. I asked her when to dig them up a few weeks ago because I wanted to see if we had a crop and she said when the foliage turned brown. A couple nights ago the temp dropped to 23 degrees and sure enough all the foliage died!!
Everyone was outside enjoying the beautiful 60 degree relapse in our unpredictable fall weather for “Friend Friday” and I decided to take a look. Everyone got in on the fun and started digging like crazy and we hit a gold mine! I was amazed that some of the tubers grew so large.
