I know quite a lot about wild plants, but little about ferns. The last couple of years I have been curious about the Ostrich fern, or Fiddleheads (Matteuccia struthioteris) as they are also called (strutseveng in norwegian). Because people are eating them, and I am very interested in edible, wild plants. I think I know now how it looks, and also were to find it, and there are thousands not far from were I live. I would never eat any plant I am not hundred percent sure about, and that should apply to all. Anyway it was too late. The name Fiddlehead is the shape of the fern when it is rolling out early in the spring, and thats the time when it is eaten. So maybe next year.
There are more photos of this fern in my green photo gallery.
