1. Young sunflowers track the sun across the sky every day. Through a process called heliotropism, young sunflower stems grow faster on one side during the day to tilt the flower head from east to west, following the sun! Once the sunflower fully matures, it stops tracking and faces east permanently to stay warm for early-morning pollinators.

2. The largest flower on Earth smells like rotting meat. Native to the rainforests of Sumatra, the giant Rafflesia arnoldii flower can grow up to 3 feet across and weigh 24 pounds! It produces no leaves, roots, or stems, and attracts pollinating carrion flies by releasing a foul scent resembling decaying meat, earning it the nickname "corpse flower."

3. Broccoli, cauliflower, and artichokes are actually unopened flower buds. If farmers don't harvest these green vegetables, the tight green heads bloom into bright yellow and purple flowers!

4. Moonflowers only bloom at night. While most flowers open during the daytime to greet bees and butterflies, night-blooming flowers like the Moonflower open their petals after sunset to attract nocturnal pollinators like night-flying moths and bats!

5. Vanilla flavoring comes from a climbing orchid flower. The sweet vanilla used in ice cream and baked goods comes from the seed pods of the Vanilla planifolia orchid. Each flower blooms for only a single day and must be pollinated immediately to produce a vanilla bean!

6. In 17th-century Holland, tulip bulbs were more valuable than gold. During a famous craze called "Tulip Mania" in the 1630s, rare marbled tulip bulbs became so highly prized that a single bulb could be traded for an entire estate, a ship, or years' worth of food!

7. Flowers existed alongside the dinosaurs. Fossil records show that the earliest flowering plants (angiosperms) evolved over 130 million years ago during the Cretaceous period, blooming alongside plant-eating dinosaurs like Triceratops and Stegosaurus.
