A friend of mine brought this to my house and said she dug it up because she said I needed more house plants. She said it was from a forest near her house and she dug it up. There weren't many roots left but a big chunk of the main one. I wanted to know what kind of tree this is and if it is possible to grow it indoors all year. I hope so, otherwise I'll try to plant in outside before winter. I put it in Miracle Grow potting mix that fertilizes it for up to 3 months and I left it outside so it would feel more at home for now. I hope I can grow it indoors because I think it's a beautiful baby plant.
Lycopodium dendroideum, or similar. It's a clubmoss not a tree. http://www.friendsofsleepingbear.org/ferns.htm
