Final answer:
A boutonniere should be placed on the left side where the filler flower is in a box.
Explanation:
A boutonniere should be placed in a box by placing the flower on the left side where the filler flower is. This ensures that the flower is prominently displayed and balanced with the filler flower. Placing the flower directly on the bottom or placing the leaf directly on the bottom for protection is not the correct way to arrange a boutonniere in a box.
