Comercial flowers

In class we spent a good amount of time discussing the view of positive aesthetics. As you all should know positve aesthetics has the view that nature untouched by human interaction is most beautiful.  The other day I got flowers, crazy daisies, my favorite. Anyway, I got thinking about the commercial flower.  Yes, sure its nature, its a living flower, but it is so heavily modified by humans.  Certainly they are modified in order to make them more aesthetically appreciated but, I think those with the view of positive aesthetics would think otherwise.  Commercial flowers are often grown with pesticides, genetically modified and artificially selected, dyed and ultimatley taken out of their natural environment and placed in a vase that sits on a table top until they die. Clearly, commercial flowers have been marked by humans.  I think those in positive aesthetics would argue that comercial flowers are not beautiful and should not recieve a great deal of appreciation because they are certainly far from pristine, untouched, pure nature.
