Tansy is said to be an insect repellent. Used as a companion plant, Tansy can help keep insects away from your garden. You rarely find one of these plants munched on by an insect. As I was traipsing around behind the farm, I noticed the Tansy were covered in insects -- from what I could tell, beneficial insects like bees and very small wasps. Imagine if we were like Tansy. What would life be like if we were able to only let the genuinely good people in, and all of the destructive people bounced off of us to go down the road and eat someone else’s life? It probably took Tansy hundreds of years to evolve into such a smart plant. People don’t have to wait hundreds of years. We get to choose.
