The Black Tulip. I found it after finishing Dumas' The Count of Monte Cristo. The Black Tulip begins with a historical execution of two men in the Netherlands in 1672 and moves into a fictional story of two men attempting to be the first to produce a black tulip. Along the way a character is arrested and sentenced to be hung. History meets fiction in a very entertaining story.
I did some research and apparently there is no truly black tulip. The closest to black that tulips come are deep purple.
