In terms of what species of plant, the flowers are geared to be attractive to pollinators, often specific pollinators such as a bee - evolution took care of that a long time ago - flowers that were attractive to pollinators were always going to set more seed. As for flowers that still have nectar - they haven't already been visited and the nectar taken. If you watch a bee at work you will see that they can't detect that but most flowers will continue to produce nectar or they will wither once they have been visited and pollinated.
