I read where you could grow plants from the stalks of produce items we get at the grocery. On March 21, 2012, I took the picture of a turnip green stalk that I stuck in a cup of water and placed it on our kitchen windowsill just for curiousity. By the next day, it had started to grow! It is now the *bigger* plant in the second photo. Three days ago I stuck a celery stalk bulb in water and as you can see, (smaller plant in picture #2) it is growing already. Amazing!
I will be experimenting with other plants.....
