I found a little bit of Louisiana in Texas, today.
The Fleur-de-lis has come to be the symbol of Louisiana.

In French, fleur-de-lis literally means "lily flower". It may come as no surprise that an emblem found all over the state
of Louisiana has its roots in a flower from French culture, stemming from the French colonization of the Americas, namely present day Louisiana.

After an on again, off again relationship to the French flag over a period of several revolutions, the Fleur-de-lis eventually
made its way to America with Europeans going to the “New World,” mostly from France. For these French settlers it
became a reminder of the home country for their new lives in Louisiana, found on coats of arms and early North American
flags to designate areas settled by the French.

To set things in stone, governor Bobby Jindal signed a bill in 2008, which would make the fleur-de-lis an official symbol of Louisiana.
