As many here have commented, the map is pretty bad and lots of these are not officially recognized as national flowers.
Having said that, actual national flowers, much like national animals, are often just whatever commonly grows in the country (assuming there is one flower that really sticks out).
They don’t have to be unique, because you’ll have a flag or a coat of arms for that purpose (which may portray that flower or animal, for what it’s worth). So, they’re rather just part of the “national branding”, if you will.
Cool. I didn’t know we had a national flower.
But there are a lot of flowers in Europe, why are so many repeating? Is it really your national flower if 5 other countries have the same?
I would guess that is because a lot of these are just made up. For example, Germany does not have a “national flower”.
