The Californian Poppy is a vibrant, sun-loving flower known for its silky, cup-shaped petals in shades of orange, yellow, red, and pink. This drought-tolerant annual (or short-lived perennial in warm climates) blooms profusely in poor soils and is perfect for wildflower gardens, borders, and rock gardens. The flowers open in full sunlight and close at night or during cloudy weather.
