Cornflower
Centaurea cyanusAlso known as Bachelor's Button, Bluebottle, Boutonniere Flower, Cyani Flower
Cornflowers feature intense, electric-blue blossom heads composed of ringed disc and ray florets that stand atop slender, branching stems. Once a ubiquitous weed across European grain fields, intensive modern agriculture and heavy herbicide use drastically reduced wild populations in its native range. Today, these hardy annuals are widely cultivated in gardens and wildflower mixes, providing a vital source of nectar for bees and butterflies from late spring through summer.
