Tree ferns with Snow April 08

Did all your Tree ferns survive the snow in April Treesandthings? We have one but we keep it in a pot so we can keep it in the greenhouse for protection in the winter?

I had put straw down the crowns of all three tree ferns. This was enough to keep the cold off etc. We only had snow in April so they didn't have to put up with much. But yes they are all healthy now and love living planted in the soil. I shall take a pick of them today 23/6/08.
