I only have three plants that live in the house year around. 9 months out of the year, the fight would be between my Peace Lily, my philodendron, or the Money Tree. The Money Tree would probably win out as it is small enough to carry out. I don't think I would have time to get the dolly for the Peace Lily in a fire.
In the winter, that would be a tough one since many of my tender plants come into the house. I would grab up one of my plumeria, I suppose? Gosh! Why make me choose? This is like Sophie's Choice!
