The English national flower is the rose, right? The rose, however, is not confined to the British Isles alone. There are species of roses native to Europe, but also to North America and to Asia, including Japan.
Needless to say, however, nobody accuses the English of "stealing" the rose for their emblem.
The Scottish national flower is the thistle, yet the thistle is not confined to Scotland alone. Its native habitat stretches from Portugal to Scandinavia to Kazakhstan.
Needless to say, however, nobody accuses Scotland of "stealing" the thistle, just as no one accuses France of stealing the lily ("fleur de lis"), and so on.
I think you have guessed what's coming...

Gives a whole new meaning to "flower power", doesn't it?
