How to Propagate Perennial Bachelor Buttons

Perennial bachelor button, Centaurea cyanus, is a wildflower that produces bushy leaves and small, blue, purple and pink flowers. Bachelor button is propagated through seeds, which you can start indoors a month before you intend to transplant in the garden. As long as your bachelor button plants bloom in the first year, you will not need to repeat the process the next year, as the plant is a natural self-seeder.
