Yeah see when I was going on an iris hunt a month or so ago I got really confused as to the floral part of iris perfumes, because iris flowers themselves have no floral scent, they smell like juicy green unscented petals! I got a hold of some violets which were exactly what I had thought iris flowers smelt like, from the various iris perfumes I'd tried. I'd be very interested to smell iris absolute (if it exists), iris root essence and violet absolute next to each other.
Anyways sorry to hijack your moment there. Dior Homme is a very nice iris, one of the best recent release designer fragrances I know of. The cult of Hedi Slimane doesn't hang around for nothing!
