Funny, I have some right here, and I've been wondering the same thing. It is really "abstract" for a home fragrance/room scent.
I think that it has the usual suspects of "Provenšal" scents, it's just really well-blended. There has to be some lavender and verbena in there. Something else is softening it all up.
My little bottles of room fragrance have ingredients on them - I'm using the kind with the stick diffusers. I would look at the ingredients for this one, but I tossed it. Do you still have yours? I bet people here could decipher it.
