Why do flowers have fragrance? To attract the bees, or the ants, or the moths or butterflies or any of the other pollinators that will help that flower to reproduce. Plant scents not only attract pollinators, they are more subtle than that, possibly more subtle than the human nose knows.
Floral scents are composed of many, sometimes hundreds, of volatile organic compounds, or VOCs. These VOCs can differ in their contents or amounts by pollinated (I'm done stay away!!) and unpollinated (Hey, bees, over here!!) flowers.
Not only that, a pollinated flower can send a chemical message to nearby buds to open up and have their turn to be bee'd.

Depending on the type of pollinator a flower has, the VOCs will be emitted at differing times. Bee attractors send their scents in the day when the bees are at their buzziest, while moth attractors will emit their fragrance after dark. Great for planting near the back verandah or under windows, such species include nicotania, cestrum nocturnum and hoyas. Many of these species are white, as an extra help for the moths.
