Thanks for the tip, seab- that's a really nice looking sweet potato. I'll keep an eye out for it in the health food stores/organic sections and give it a trial run.
Your patch was sure pretty- and big! The Evangeline vines were especially pretty to me- perky and purpley. I grew them in loose, hilled up soil that I covered with black permeable row cover to increase the heat of the soil a bit and control weeds and the Evangeline grew in the same rows with Beauregard. The main difficulty I had with every other sweet potato that I tried before Beauregard was that the tubers all had sunken dark spots on them that increased in size during storage- like a dry rot of some kind. Beauregard has never had that and produced lots of big tubers so we stuck with it. I would like to find a variety that was a more reasonable size though...maybe Red Garnet/Diane will work for us.
