The one vegetable that continues to grow through the cold weather is the lettuce. It's a Romain mix that I put out several weeks ago that while it's growth is slow is still growing. Lettuce can handle light frosts and has already been through 4-5. Just add a little coldframe over it and who knows how long it will keep growing! Of course Tennessee has a mild winter so if you live north of me your lettuce might not last as long.
I planted some oregano seeds while my squash was growing in the hopes that it would ward off my number number one most despised garden pest: squash vine borers. Oregano is listed in many charts as a generic works against nearly everything companion planting herb. It didn't work. I may have to try a second organic strategy and place row covers over the squash when the borers are actively reproducing. The thing about organic pest control practices is that they are not fool proof; what works for one gardener may not work for the gardener next door. The result of my companion planting of oregano with the squash ended up with quite a bit of oregano. Two raised beds are completely covered with it and will need thinned in the spring.
Another raised bed is completely covered with cilantro. I read once on a blog (sadly I can't remember where otherwise I would link to it) where cilantro was by volume the most expensive grocery vegetable. If that's the case then I'm doing very well! This cilantro was sprinkled over the garden after my first plants of the year bolted.
