Bachelor Button Blue Boy
Centaurea cyanus
Annual. In addition to the dazzling sky blue flowers, Bachelor’s Button Blue Boy (also known as cornflower) is also drought tolerant. Flowers can be used dried or fresh cut, while the edible petals make a stunning garnish. Bachelor’s button will "naturalize"; it self-sows the next year for another crop of blue flowers.
