Black Magic Bachelor's Button is a striking cultivar of Centaurea cyanus that brings deep, dramatic color to full-sun gardens. Growing 20 to 24 inches tall, this variety produces the moody blooms that give it its name, a departure from the brighter blues and pinks of traditional cornflowers. Direct sowing in spring or fall makes it a straightforward addition to cottage gardens, wildflower meadows, or cutting gardens, rewarding minimal fuss with consistent, elegant flowers.
