The celery self seeds very easily. I have hundreds of small celery plants now, many of which will survive the winter unprotected. If they didn't it would not matter, as many overwintered seeds would sprout in the warmer spring weather. Plus there are a bunch of volunteers inside the cold frames, so they should survive the winter unscathed. To flower, then go to seed. I will never lack for hollow celery.
