"Butterfly bush" in the UK is a common name for buddliea.

Buddleja and Buddleia are both accepted spellings (so far as I know);
and the pronunciation is the same. I don't write or think Buddleja
because I think it's a clumsy word shape, though at least it should
remind me that the E comes after the L :-)

But that's not what you wrote. You wrote buddliea, twice )
