I've had good luck with tomatoes in January - if I see them at my local HD, I will be tempted to buy some, as I did not plant seeds this year. My growing area has been taken over with chilies, and they are doing extremely well for me right now.

My Jaune Flammee is still pumping out pretty good tasting maters despite the fact that several nights have been at or in the 40s. Also Orange Bell and Joe E Parker pepper plants loaded up late when it finally cooled off a bit and are ripening, slowly, but ripening none the less. I also have ripening fruit on Dwarf Wild Fred and a Hybrid Paste whose name escapes me at the moment. I'm sure they wont taste as good as if ripened when nights were warmer but will probably taste better than store bought!
