The California State Flower is the California poppy (Eschscholzia californica). This vibrant orange flower was designated as the state flower in 1903. It is known for its bright color and delicate petals, which open in the sunlight and close at night. The California poppy thrives in the state's diverse climates, particularly in the coastal and desert regions. The California poppy is not only beautiful but also resilient. It can grow in poor soil and is drought-tolerant, making it well-suited for California's environment. This flower is often associated with the state's natural beauty and is celebrated during the annual California Poppy Festival.
