I do it all the time....it is the sweetest part of the celery......also you put a 2 inch root in a little bowl with a little water...don't let it dry out and another celery will start........almost l like in the middle turns dark first then the green celery will poke thru.........we planted that....then you can take cuts off it............makes delicious potatoe salad....a little stronger than the one from the store. You also can plant it in a pot and grow it on a sunny window sill.
