You will need to determine the sun density of the window boxes to make the proper selection of plants.
Some possible plants; Sweet Potato Vine, Fiber Optic Grass, Dracaena, White Licorice Plant, Coleus, Frosted Curls,
Summer Snapdragon and Coleus.
Succulents and Sedums make lovely window box displays.
I would suggest a visit to your local garden centers and greenhouse and see the local selections. They often have plantings that can give you a nice idea on mixing plants.
