  Tomatoes

  

  Anyone who loves Italian cuisine knows that there's nothing better than plucking a vine ripened tomato and fresh basil from the garden. But these two also do well in the same conditions and basil repels tomato hornworms.

  Eggplant

  

  Eggplant often falls victim to many of the same pests as tomatoes, including the tomato hornworm. Since basil repels the tomato hornworm, that makes eggplant and basil excellent companions in the garden.
