I am one of those gardeners who is very challenged when it comes to keeping a plant alive in the house. If something comes into my house, you can assume it will die a pretty fast death. The only thing I have any luck with are forced branches of forsythia or quince living in a vase of water in the dining room, and I believe that's because they are the first signs of spring, and I actually give them some attention. I don't even want to think about how many orchids, begonias, ferns, and other poor things that I've killed.
I am quite proud of the fact that I have actual living things in the dining room now, though, and they've been there since before Christmas!.....and they're thriving!
