Cold frame success!

Last fall, we created seed tape with a few of the students using spinach seeds, and we planted the tape in our cold frame box.  We knew we were planting later in the fall than normal, but we took a chance to see if we would get any spinach.  Unfortunately, it became very cold quickly and the snow began to fly.  We assumed that the spinach never took because of the cold weather.  Much to our surprise, we checked the cold frame this spring and the spinach had re-seeded itself and we currently have spinach sprouting in the cold frame!
