I now would like to present to all of you good people an update on just how long a pumpkin can last. Now we didn't go and perform any long lasting pumpkin treatments on this pumpkin. A matter of fact we just let it do it's thing and had nature take it's course. This particular pumpkin, which was purchased prior to Halloween in October of 2013 lasted all of the way until May 11th 2014, which is Mother's Day. It was a Thanksgiving Day pumpkin, Christmas pumpkin, New Years Day pumpkin, Valentine's Day pumpkin, Easter Pumpkin, a couple of people's birthday pumpkins, and now finally a Mother's Day pumpkin. I don't think I missed any holidays, and I know it won't make it to Memorial day. The pumpkin that is pictured here was taken on Mother's Day, and we are proud that it lasted well over half a year, and survived past the expiration of so very many of it's pumpkin cousins and counterparts. Thank you for waiting so long for the official results for this question, and Ericdierker gets the best answer with the closest answer.
