The language of flowers is not a complicated code, and it isn’t intended to be a cryptograph. While composing sentence-long messages with floriography is possible, it is not particularly complex. For ease of reference, this guide is organized by meaning, not by flower. It includes bloom cycles, taxonomic names, pictures, and any other facts of interest such as typical clime or edible/medicinal uses.
This guide contains only European, North African and Eurasian flora (at least, I’m pretty sure. I may have fudged it up in some places).
Flowers have been used as a form of communication for a very long time. If you’re writing a period piece or just want to be sentimental, then this resource could really help you out. Hmm, I wonder if spies have ever used flowers to send messages………….
