A few weeks ago I found an interesting blog about craft, diy, food, and gardening called 17 Apart. One of the articles I found especially interesting was about re-growing celery from the base. I happened to have some celery in the fridge, so I chopped off the stalks, put the base in a dish of water, and waited. Sure enough, little celery leaves started growing out of the center! This got me thinking that maybe I could grow a whole little indoor garden to hold me over until my local CSA starts up again in June. Even if I don't end up with a lot of edible produce, it will still be a fun project.
I also read a post about doing the celery thing with bok choy and gave that a shot too. In the week and a half it took me to plant everything and finally get around to writing about it, the bok choy has grown significantly and I planted it next to my celery. (I realized the leaves went down farther than I expected, so I later trimmed down the white parts to speed things up.)
