                                Recent scientific studies have revealed a surprising truth: some flowers naturally produce caffeine in their nectar to influence pollinator behavior. This discovery reframes our understanding of plant-insect relationships, revealing that flowers with caffeine are not just passively attracting visitors but are actively using a natural stimulant to improve their reproductive success.
