Connecticut Field is a great pumpkin for jack-o-lanterns. Howden is also good. These are both pepo types.I may try jal_ut's suggestion and grow a few Connecticut Field vines next year.
My big ones this season were Prize Winner F1 Hybrid. It is a maxima type.
Dill's Atlantic and Big Max are maximas too.
I saved the seed from my largest pumpkin. Since it was a hybrid to start with and I had other maxima squash (Hubbard and Banana plus a hybrid) in the garden this year, they could be crossed again. No telling what a feller might get next year, but it will definitely be a pumpkin. You can have some seed if you want to try?
I paid $1.00 each for the seed of the Prize Winner F1 Hybrid. Right now they are out of stock every place I have looked. Maybe the new stock
hasn't came in yet?
