Cornflowers: A Timeless Bloom with Storied Uses

Once a common sight in fields and along roadsides, cornflowers (Centaurea cyanus) now thrive primarily in gardens as a popular ornamental plant. Known by many names, including bachelor’s button, bluebottle, bluebow, and blue cap, this striking blue flower has a rich history of use dating back to ancient Egypt. For centuries, its vivid blooms peeked through fields of cultivated grains like corn, wheat, barley, and oats. The plant’s tough stems often resisted the farmer’s sickle, earning it the nickname “hurtsickle.”

Cornflower petals have long been cherished in traditional wellness practices. In European folk herbalism, the flowers were used similarly to blessed thistle, valued as a tonic herb, and often blended into teas for both their visual appeal and beneficial qualities. Their vibrant purple-blue petals remain a popular addition to potpourri, lending both color and a subtle, sweet fragrance. Beyond teas and potpourri, cornflowers are infused into baked goods, cosmetic recipes, and even used as a natural watercolor dye.

Cornflowers are part of the Asteraceae family and grow to heights of one to three feet. The plant features long, narrow, alternate leaves covered in white, downy hairs, and its solitary flowers bloom atop tall, erect stalks. These brilliant blue, star-shaped ray and disc flowers persist through summer. The vivid blue hue of the petals comes from protocyanin, an anthocyanin pigment responsible for turning roses red. While originally native to Europe, cornflowers have since naturalized across the globe.

Folklore and Symbolism
Cornflowers are steeped in rich folklore. The genus name, Centaurea, pays homage to Chiron, a centaur in Greek mythology celebrated for his botanical knowledge and healing prowess. The species name, cyanus, honors a Greek admirer of the goddess Flora who favored these flowers. Historically, cornflowers were worn by young men on their lapels as a symbol of love; a quickly wilting flower was said to indicate unrequited affection.

As the national flower of Estonia, cornflowers hold symbolic significance for various European political parties and educational institutions. They have inspired famous authors and artists, appearing in literature and paintings alike. Beyond their social and political symbolism, cornflowers have represented fertility and renewal since ancient Egypt.

Modern Uses
Today, cornflowers continue to be valued for their beneficial properties. The flowers are often steeped as a herbal infusion, added to teas, or incorporated into potpourri blends. Their versatile beauty and gentle properties make them a beloved choice in herbal and artistic applications.
