What is the Science Behind Night Blooming?
Certain flowers evolved to open at night to suit their natural pollinators. When the sun rises, bees and butterflies pollinate day-blooming flowers. After the sun sets, night-blooming flowers attract moths, bats, and other nocturnal insects.
This has an environmental advantage. At night, cooler temperatures help to reduce water loss. Additionally, the absence of harsh sun rays means that delicate petals last longer.
Without being able to see so well in the dark, how would pollinators know which plants to pollinate? Instead of bright colors or patterns, the night bloomers appeal to the scent. Their “perfume” acts as a natural signal, emitting stronger scents to guide moths and bats.
What Makes Flowers Bloom After Dark?
Aside from pollinators, other factors trigger flowers to bloom at night.
Photoperiodism, or light sensitivity, is like an internal “clock” in plants and animals that responds to the length of light or dark cycles, and some species are triggered by the latter, prompting them to open when sunlight fades.
As mentioned before, the environmental advantage of cooler air signals to the flower that it’s safe to open, as petals are protected from sunburn or dehydration. The flower’s pollen is also protected from daytime predators, and blooming at night also reduces pollination competition.
