Although I study sunflower, even I was surprised to learn that most of the world crop originates in California. The Central Valley is the incubator for seeds that then get shipped around the world and grown into the plants that provide us with sunflower seeds and sunflower oil. Those thousands of acres of buttery yellow blooms create the blooms elsewhere next year!
