The world's largest water lily Victoria amazonica is a national flower of which country?

Stands to reason it was Guyana with the other answers being all European countries.

I'm very happy to see this beautiful lily from my former homeland. Praise God.

I didn't know that but I guessed it right because the answer made sense to me.

The western world discovered this plant in the 1820s and named it Eurayle Amazonica. Then in 1837, when Queen Victoria came to the throne, the Royal botanists renamed it Victoria Amazonia in honor of their queen.
