40 Days and 40 Nights of Fragrance Notes: Iris

What does the iris note smell like?I think it smells rooty and slightly powder-like.It can be confused with violets but it is less candied or green. It is more bitter, damp and earthy.I have seen it described as carrot-like, papery, raw potatoes, woody, soapy,or plummy.Mr Luca Turin describes iris more romantically and quite simply perfect. This is from his review of Frederic Malle's Iris Poudre
