Wednesday Lagniappe: Green Flowers?

I borrowed an electronic copy of this book from a public library, just for fun.  I was interested to see if the book could convince me that green flowers were worthwhile in the ornamental garden (this former Jersey girl likes her bright colors).  I realized, after reading it, that I do have some plants with green flowers already, that I enjoy: a hellebore (Christmas rose) and two euphorbias (spurges).  I guess I was biased against green flowers because so much else in the garden is green already, but green flowers can be unexpected, a surprise as you meander down your garden paths.  This book, with its lovely photographs of green flowers, convinced me that they have a place in my garden.
Happy gardening!
