Fleur

Fleur means "flower" in French. Though France doesn't have a national official flower, the fleur-de-lis (which was a symbol of the French Royal family) represents the French tri-colored national flag (alongside the blue corn flower, white marguerite, and red poppy). All flora mentioned are widely considered French national flowers.
