Re-Growing Celery

I saw this post on Pinterest last spring and I thought, if this really works, why isn’t everyone doing it?  I throw many celery ends away, as well as romaine ends, so I got out some pots and decided to give it a try.  I followed these instructions, http://chickensintheroad.com/farm-bell-recipes/re-growing-celery/, and you can see by my picture that it really works.  I have several lettuce and celery plants in my main vegetable garden and they are doing well, and I continue to plant my celery and lettuce and give it away to family and friends.
