Tree fern

I think, the jungle is far too "empty" and doesn't have as many variants as it should have (in my opinion).

One thing I suggest to fix this are tree ferns. Tree ferns are minimum three, maximum up to seven blocks high and would spawn in jungles and jungle edges.

If you destroy tree fern with silk touch, you get paper or even something new like parchment or papyrus from it.

Anyway, tree fern would definitely improve jungle life!
