I have a plant that I got from someone else and am not sure what it is. It looks alot like an Arbicola type house plant. I am wondering if anyone knows what to with one that decides to wilt and die. I don't know if it had too much sun or was to close to a window and got cold (from the winter) It is trying to die--leaves are turning dark and it is just hanging now. Anything I can do to save it?
