Thanks for the information! I guess I will take a pass on the idea of a purple sweet potato, or if I decide to try one, I will give Purple a try and see how it does in my area.
I would need slips in the ground the first week of May to grow a 140 day sweet potato. In most years, the weather here would probably accommodate it, but it seems like it is almost impossible to find slips anywhere that early in the season.
Shelleybean, I've never really considered a white sweet potato. I guess it is more mental than anything. It just doesn't seem right that a sweet potato should be white.
The descriptions of white sweet potatoes do sound good. What are some good white varieties? In one thread I read, someone mentioned a purple skinned / white fleshed sweet potato from Sandhill. I don't recall the name, but would remember it if I saw it.
