Reminds me of an old show from the 50's when every living plant in the back yard where a woman lived was poisonous. The vegetation would kill anything it touched. Her father did this to keep her alone from unwanted suitors. Well her suitor touched it and became like her. I think it kept him from cheating. Don't remember the name of the show. I also think of he insurance you would need to carry in case an outsider touched this plant. Thanks for an intriguing blog.
