It depends on your climate. In warmer climates, turnips will continue to grow, albeit slowly, through the winter and then when the weather heats up, they will bolt, flower and set seed. The root is an energy store for the plant, so when I was pulled out of the ground and put into the refrigerator, that didn't kill it, just put it into hibernation. It's not going to do like a potato and make more tubers underground, but if you keep clipping the tops, it can bush out and form several tops all sharing the same bulbous root.
Here in Georgia, the green tops are probably more popular than the roots. And then there are those that can't decide, so they cook up the diced root up with the greens. From your post, it sounds like you haven't been introduced to turnip greens, but they can be cooked up and used interchangeably with cabbage or broccoli. The only difference is that they don't have a texture that holds up to cooking like the other two; they tend to have the same consistency as spinach does after cooking.
