Collecting and Storing Bachelor Button Seeds for Next Season

To save bachelor button (Centaurea cyanus) seeds, wait until the seed pod turns brown. Snip off the whole head and place it in a paper envelope to finish drying. Next spring, separate the seeds and start them indoors 6 weeks before your last frost date—either in a sunny south window or under grow lights. Direct sowing is less reliable.

Note: If your plant was a hybrid (e.g., named variety like ‘Blue Boy’), the seeds may not produce identical plants; they often revert to a parent form.

Store the envelope in a plastic container in a cool, dry place like an unheated garage.
