Irises have a long and rich history. The Fleur-DE-Lis, a stylized representation of the iris, has a long history with French monarchy, beginning with Clovis the I a Frankish king whose empire birthed the French state. Legend claims that when Clovis became a Christian he dreamed of an angel who gave him an iris to commemorate the event. After his dream, Clovis adopted the iris as his emblem.
Fleur-De-Lis translates as “flower of Louis” and gained the name when Louis VII, who went on the Second French Crusade in 1147, used the emblem on his banner.

The name, anglicized, means "lily flower", and the symbol is in fact a stylized Iris pseudacorus L.. It was adopted by King Philip I of France in the 11th century.
This is more tasteful.
