This year I harvested several oddly-shaped tomatoes. Here's the strangest one of them:
I picked this guy while still green because the temperature outside had dropped below freezing, and some of the others on the vine were already starting to get soft spots. This might have happened because the blossom was set when the temperature was below 50 or so degrees. This was, in fact, a late season (October) tomato, and I picked it this month.
Either way, I'll take this little guy over any of those uniformly round and red and tasteless specimens in the grocery store!
