         | only I guess.

         | I have a 'Honey Perfume' that smells nice, but most of the
         | other varieties I have only have very faint scents.

         | I concur. Even roses which are extremely expensive and
         | nominally "highly scented" don't smell at all, anymore. I used
         | to have to go on a hunt for a varietal with scent, and now even
         | with a lot of hunting, I can't find them anymore.
         | 
         | The problem is apparently that some enzyme that makes scent
         | also tends to break down the flower. So, the "lifetime" of a
         | cut rose is inversely dependent upon the volume of scent.
         | 
         | And, since everything is shipped around the world from the
         | absolute lowest cost area, "lifetime" becomes the only goal
         | with everything else being secondary.
         | 
         | Thus, we have roses with no scent.

       | Your rose smells nice because it was bred to smell nice by human
       | breeders. All the different varieties of cultivated roses that we
       | have today are the product of hybridizing and selective breeding
       | ("artificial selection") of twelve or so wild rose species; a
       | process that has continued over hundreds if not thousands of
       | years.
       | 
       | While not a hard and fast rule, most plant species with strongly
       | scented flowers usually are white (jasmine, gardenia, etc.) and
       | pollinated by nocturnal animals like moths and bats. (A great
       | counter-example is corpse flowers, which use scent to attract a
       | completely different guild of pollinators).

       | This is all about chemistry and genetics. But nothing on 'why
       | roses smell nice'.
       | 
       | It's really a puzzle. Why on earth should Homo Sapiens consider a
       | rose's smell to be 'nice'? Dogs like roses' smell about the same
       | as shit. They don't give a damn.
       | 
       | Further, why are rainbows pretty? Why is a waterfall inspiring?
       | And on and on.
       | 
       | You have to have some kind of special model to explain this, I
       | think. Something beyond simple reproductive survival. But I don't
       | know what.
       | 
       | Anyway, interesting that we all smell slightly differently! So
       | indeed qualia is a bigger issue than we may have thought.

         | suppose.
