Once our shadows begin to lengthen towards the north and the sun just doesn't quite crest the southern hill behind our home, these lusty heads of summer begin to transform to a smorgasbord of seed.  They become somewhat bedraggled looking and I have had more than one visitor ask when I will cut them down to "clean up my garden for the Autumn."  Their lost lustre (petal-less, drooping and dismal) is but a facade for this is the season of their true crowning glory; this is when they give!
