Winter Tomatoes?

I had started a new compost heap in an old palm tree tub. Then I threw some used compost on top of the remains from the kitchen, to stop the dogs getting to it. Then early September we got some rain, and next thing I knew I had melons and tomatoes growing in the tub. The other day, I lifted 6 of the tomato plants out and replanted them in a sheltered part of the garden. They seemed a bit big for transplanting, being at least 1 foot tall, and it is now early November which has just GOT to be too late for them. Or is it?
I'll let you know.....

My Palm Tree

It's possibly a Trachycarpus fortunei but I'm ready to stand corrected.
