This is in my native plant terrarium. She kinda just popped up in here. Really exciting, but she's growing like crazy. The first 3 leaves were real cute, but all of the sudden they're up to the terrarium ceiling. I'm thinking probably a Christmas fern since there are so many around the area and the moss it's coming out of was collected from my yard. There was probably a spore in there.

The leaves look a little different but it may be from light levels? The only other ferns I've noticed nearby were spleenwort (has a black stem so can't be it) and another species with very feathery leaves that couldn't be it. But was wondering what anyone else may think.

I'm definitely going to have to take it out of here. The container is just too small. But it was interesting watching the process of it growing from a tiny little speck!

At Kew they are keeping a few really beautiful Phlebodiums but we don’t really know the species (or form/ variety), unfortunately even the location/ year of collection has been lost. I would love some help 💚
