You know plants have the ability to target specific threats. Tobacco plants when attacked by heliothis caterpillars will send out a chemical attracting wasps to kill just those caterpillars. We don't know how plants obtain these abilities, they just evolve very rapidly.

Nursery Owner:
Plants have the ability to communicate with other species of plants. Trees can communicate with bushes, and bushes with grass, and everything in between.
