Centaurea cyanus, commonly known as the cornflower or bachelor’s button, is an annual flowering plant in the Asteraceae family, native to Europe and now naturalized in many temperate regions worldwide. It typically grows 30 to 90 cm tall, with slender, gray-green, lanceolate leaves and fringed flower heads in vivid shades of blue, though pink, white, and purple forms also occur. Blooming from late spring to summer, Centaurea cyanus adds brilliant color to meadows, borders, and wildflower plantings. Once a common sight in cornfields—hence its name—the plant thrives in full sun and well-drained soil. Its nectar-rich flowers attract bees, butterflies, and other pollinators, while the blooms are often used as cut flowers or dried for ornamental arrangements. The cornflower’s enduring charm and easy cultivation have made it a beloved symbol of simplicity and rural beauty.
