I picked up this beautiful fern from an estate sale 4 months ago. I've never grown ferns before, but I've grown very attached to this plant! I do not know what type of fern it is. Any guesses? It's actually two plants in one pot, and it may be two separate types of ferns. I'll post closer up pictures of the leaves.

It's quite potbound, so I was thinking I might try to divide the two plants. Does anyone have any tips on how to do this without damaging it? Would I be better to just replant it into a bigger pot? I really love this plant, so I'm very nervous about messing with it.

Also, it looks like it has little new growths on some of the leaves! Are these separate plants, and can I take these new growths and plant them? How neat it is to see! I'll post more pictures of this.
