What happened to my Lilium candidum?
Last year I bought three Lilium candidum bulbs and planted them in three 10 liter pots. (About 3cm deep) The temperature in last winter was -17C. I did have protection around the pots, but not on top of them. Now there isn't any sign of growing. I wonder what happened to them. Are they frozen? The photo below shows how they look like now.
