I had read an article a while back that you could sprout a new celery plant from the base after you cut the stalks off. I was intrigued. This means that as long as you keep the plant alive, it will continue to produce new stalks of celery. Perpetual food source? Sign me up! I had purchased a bundle of celery to cut up and put away for my lunches, but then I caught the "lazies" and never cut it. Eventually it was too rubbery for me to want to eat, so I figured I had better plant it.
