What's Growing? Horseradish!

Our Seder plate includes horseradish and I stuck the top of the root in some water and it's growing quite vigorously!  I'll wait for some more roots and then try planting it outdoors.  Has anyone tried doing this?  Did it grow?

I have done a lot of baking and cooking recently, but have not had the camera out with me, thus no photos of food!  Photographing while cooking, baking and cake decorating takes a lot of time and coordination and it's been a little rushed and haphazard in the kitchen, not conducive to pretty pictures.  I baked some favorites for Seders and Passover including my favorite Mocha Fudge Cake from the Frog/Commissary Cookbook, Mini-Cheesecakes, Coconut Macaroons and Caramel Matzoh Crunch.  Let me know if you want recipes and I'll be glad to post them.
