It could be a wild cucumber vine.
Good call. (Without flowers or fruit)
O.F.
Hay Swamp Rat, I think Plant Eater got it right.
Thanks Edibleplantguy
Someone, once, gave me a jar of fiddle neck ferns as a Christmas present. My boss, who was Australian said. "Oh, you have, Lawn Clippings"
O.F.
Greetings All,
I don't believe you have a cucumber family plant here folks. Firstly, and please correct me if you know of an exception, the Cucurbitaceae have hardly anyone who is perennial at temperate latitude, who would still be in leaf at this time of year even given this mild winter and being in Tennessee.
I believe that you have an excellent photo of an American climbing fern Lygodium palmatum. There is not much written about the American climbing fern being eaten, but Tanaka lists a half dozen species in the genus Lygodium that are edible in the fiddlehead stage (cooked) from other countries. These fiddleheads are very small however, and it will take plenty to make a sandwich.
Thanks for reading,
