In addition to Esty's observation, the great pumpkin ( )could also be a way of showing the abundant period the Shire was entering. In the book its because of Sam's Lothlorien seeds, but here it could be viewed as a general consequence of the rejuvenation of Middle-earth. Of course, I may only be remembering the pumpkin as bigger than it was (and I'd have to take a look at the FotR EE again to see how big the vegetables looked before the Quest) but that seems like a good way to give a nod to the way the Shire bloomed after the War of the Ring.
