Here are two of my "unknown" ferns....they look a bit rough because they were in a terrarium that they had really outgrown so I took them out about a week ago. I'm trying to grow them using Kokedama, which is a traditional Japanese art form that basically has moss used as a container for a plant...

Here is a picture of how you can display a kokedama "garden"...
