Since pumpkins have been mentioned, I thought I'd ask the experts.
Last year I had a little pumpkin patch in my tiny backyard garden here in Albany Park, which ended up producing one pumpkin. Here it was, a few weeks before harvest.
About ten pounds, decent orange color, a little lopsided. I decided not to carve it up, but keep it whole on my dining room table for a lazy person's autumn centerpiece (I am nothing if not lazy). I harvested it mid-October 2004 and here it sits, exactly as it was the day I brought it in. No soft spots, no signs of rotting, no maraca-like sounds when shaken. I still don't want to carve into it, because now it has become more of a curiousity.
Ever heard of the pumpkin that wouldn't rot?
