I know this is a way old post, but I've only just spotted it whilst searching 'lantana' on the forum. I too am a fan of the Lantana plant! We had a hedge of it growing in our back yard when I was a kid and whenever I smell it now I get hugely nostalgic. There is nothing in the world that smells quite like it. Unfortunately I've never come across it in any fragrances or perfumed products, but I'll keep on looking.
Edited to say: I lived in Africa then, not England!
