I used the Language of Flowers a lot in this book. It was a very important part of Victorian courtship. Unfortunately, being from Southern Ohio, Bianca is not quite as fluent in this secret means of communication.
One of my favorite ANNUALS - the fast-growing Black Eyed Susan Vine (also called the Thunbergia or Clock Vine) adds a little drama with its solid black eye, framed by sunny yellow, white, or bold orange flowers. They like full sun and vine like crazy!
