I have grown a few over the years. Hubbards (Chicago Warted and Blue) large and productive in zone 6B, can't take the 8a climate well, Moschata (Golden Cushaw, Dickenson) not a cushaw but a huge butternut. Mixta ( Green Striped, Gold Striped, Jonathan, Tennessee Sweet Potato) gold stiped is my favorite but most of them perform better than other types in the south
