I love the spiral shape of fiddleheads, the furled fronds of fledging ferns, like these ones that I spotted last week at Prince William Forest Park. I have been told that fiddleheads are quite tasty when sautéed with garlic, olive oil, and lemon, but I have not yet tasted a fiddlehead.

I have long been confused as to whether fiddlehead refers to a species of fern or a stage in its life. Your post spurred me to look for an answer. It turns out that it’s both! From fearlesseating.net:
. . . Though all ferns have a fiddlehead stage, it’s the Ostrich fern, a specific edible fern species, that has become synonymous with the words “fiddlehead ferns.” . . .
Thank you for instigating this action on my part!
P.S. nice shots! I too love to watch as the fiddleheads unfurl.
Nice details.
