Unless the post you are replying to has been heavily edited, I am at a loss to see how you could find in it either an assumption or implication that flowers themselves decided to be beautiful or that they know they are beautiful.

One could challenge whether it is appropriate to say flowers are beautiful to insects, though clearly that is intended to be read as attractive, which, empirically, they are (nor do you seem to dispute the proposition that they evolved to be that way), and there's no prima facie reason for their scent and appearance to invoke pleasure in most humans.
