Regrowing Celery??

I saw a picture on Pinterest the other day that looked like someone was growing celery from the bottom part that we throw away when we buy celery at the store.  So, I just used up a bunch of celery and thought I'd look it up.  I found info that says you can, indeed grow a new celery plant from the base of the celery.  Some set the base in a dish of water overnight, some plant right away...but put it in the dirt and cover with about and inch of dirt.  Within a couple days there is new growth. 

This is a longer piece than what I saw online, but am going to try it...next one I'll cut shorter.

Since mine has been in the fridge for quite a few days, I'm opting to put it in water overnight.

I put the celery in the dirt, covered by about an inch, 2 or 3 days ago.  Here's a picture of it today.

It's probably 3 inches tall!  Go celery.  Who would have guessed this was possible.
