Langage de flore - J.P. Troncin
J.P Troncin's Langage de flore, ou, Nouvelle manière de communiquer ses pensées, sans se voir, sans se parler, sans s'écrire is one of the relatively few books to bring an entire grammar to the language of flowers instead of simpler strings of meanings. Troncin introduces a system of ribbons that connect the various flowers, allowing for more complex thoughts to be displayed - literally, the book's title invokes a "way of communicating thoughts...without writing to each other".
As an example, the arrangement shown here (when seen entire) says, "If you love, you will be happy. There is no happiness without love. The most important good thing in our lives is a pure, gentle, and sensitive heart."
