Sweet flavor and no strings. A unique sweet potato with bright pink skin and deep-orange flesh. A clear favorite in Johnny's taste tests. Extra sweet. No need to add sugar when cooked. Very good yields of uniform, blunt-ended roots in a very concentrated set. Excellent storage potential when cured properly.
