If you have permission to dig on that land (or it is your own land) then ferns are quite transferable to the garden. Many ferns grow off each other, so just take a shovel and dig around the one you want and keep some dirt on the rootball. Place them in a bucket or plastic bag for transporting. You can do this when they are green or dormant (but you'd have to find the dead foliage to recognize them).

Cinnamon ferns do grow on the creek banks and don't mind having their toes in the water. They also grow fine in the garden, but don't always get as big as when they have lots of water and sun. Tall ferns in the woods may be ostrich ferns. Another moisture loving tall fern is Royal fern.

That's a leaf from a tree fern. It'll stay green for a while in water but will die rather than grow. There's lots of different species of tree fern, that might be one of the commonly cultivated ones, Cyathea cooperi.

I've transplanted several ferns, and they've all done well. You have to transplant them to a place that is agreeable to ferns, of course, not move them to an environment they can't tolerate.

"I picked this
leaf from a huge plant!"

It's a leaf, not a plant. It won't grow.
