This link will help you look after it. They are extremely tough compared to regular ferns. Ask me how I know. ;o) Here is a link that might be useful: Davallia...Rabbit's Foot Fern

The leaves do closely match on that one. Not exactly a stunning plant, huh? Doesn't ring any bells for anything we might have planted either. I'll watch it and see how it goes. Thanks.

I have the same in my containers, tried to identify it, seems like hairy bittercress but it never grows in rosettes like I see in google search photos. It seems to stay small, only a few (3-4) leaves per stock, grows upwards and if allowed hundreds of little plants come out in the same container. also the color is a bit lighter green. here are some pictures i just took, it’s like this from spring into fall. definetely some type of weed because nothing seems to stop it. I want to confirm if it’s indeed hairy bittercress and not a look alike plant. thank you

You have an alocasia. It looks a bit like Alocasia stingwray. If so, I did have this plant until I gave it to a friend who really really wanted one. But my experience with it was that it always lost a leaf when it gained a new one. So in my estimation, there is really nothing wrong with yours. I expect that in warmer season, perhaps one can retain more leaves as it gains new ones.
