as Dayton boy said ostrich ferns are the major fiddle heads that are consumer. nearly all ferns grow up from fiddle heads that is the immature frond of the plant that will grow and unwind. The only time I have seen ostrich fern plants in the wild was in the Adirondacks in Northern New York. I would really research the edible fiddle heads before consuming any there are ones that are quite nonhazardous to your health if eaten. on the up side ferns are rather easy to identify with some work and a good field guide. best of luck to you.
Don't tell fish stories where folks know you especially, don't tell them where they know the fish.
