Nocturnal plants are species that primarily open their flowers and release their fragrances at night. This adaptation helps them attract specific pollinators, such as moths and bats, that are active during the evening hours. Examples of nocturnal plants include evening primrose and moonflower, which bloom in the dark to maximize their chances of reproduction. These plants often have pale or white flowers, making them more visible in low light. Additionally, they may have strong scents to lure nocturnal pollinators. This unique behavior contrasts with diurnal plants, which bloom during the day and rely on bees and other daytime pollinators.
