In this section of the window box, I see a marigold, alyssum, zinnia, begonia, dahlia, Marguerite/African daisy, and verbena.
More verbena, a petunia, dahlia and geranium. (I took these photos early this morning before my sister in law had them dead headed.)
This section has a cosmos too and a beautiful orange dahlia.
Another petunia trails from the corner.
