Fun Facts
- 🌱 California Golden Poppy is the official state flower of California and has been since 1903; it blooms so profusely in spring that hillsides appear to be on fire.
- 🌱 The flowers exhibit heliotropic behavior, opening in full sunlight and closing at dusk or on overcast days—this is an adaptation to conserve pollen in cool conditions.
- 🌱 Mission Bells will readily self-seed in ideal conditions, creating naturalized drifts in subsequent seasons and providing year-after-year color with minimal effort.
