I want to invest in a plant that smells terrible. That will survive in zone 6. I have people hanging out on the sidewalk next to my house, which was fine, til someone decided to graffiti the sidewalk with a gang symbol. So I thought planting some foul smelling plants would deter them from hanging out near the sidewalk. Anyone have any ideas for plants that'll stink the place up? I found skunk cabbage, but that says it needs to be crushed in order to stink. I also found a very large plant, but that only stinks when it flowers, and can't survive zone 6. Any ideas would be very much appreciated.
