Cornflower Black (Centaurea cyanus), also known as Black Bachelor’s Button, is a rare heirloom variety with deep, dark purple-black blooms that add dramatic contrast to the garden. These easy-to-grow annuals are pollinator magnets, drawing in bees and butterflies all summer long. Perfect for wildflower patches, borders, and cottage gardens, they also make long-lasting cut flowers, both fresh and dried. Hardy and low-maintenance, this Non-GMO variety thrives in full sun and adapts well to poor soils, making it a favorite for naturalized plantings.
How to Plant
When: Direct sow outdoors in early spring or fall; can also be started indoors 6–8 weeks before last frost.
