I found seeds at Territorial Seed and ordered them. Of course if they come up for sale at Deep South I will try to get them. But I often miss out. Tried to get Mr Als Sweet potato and missed out on that. I also found Tennessee Sweet Potato Squash at Marys Heirloom seeds and got that one too. Im wondering if the Thelma Sanders and Tennesse Sweet Potato squash are the same thing. THe cool thing is that the Thelma Sanders variety originated in Missouri so I am very hopeful that it will be a good one for growing here (KCMO area). Been trying to find Evangeline Sweet Potato without success.
