General description

Bachelor's buttons bear charming and prolific flowers in hues of blue, pink, lavender, white, and maroon. Those with a true blue color are especially welcome in the garden as that color is rare in nature. Each disc-shaped flower is about 1.5 inches across, with ragged petals radiating out from the center.

Once a common weed of cornfields, as a result of modern agricultural practices it is now very rare in the wild.

Plant requirements

Cool weather annual that is easily grown in average, medium moisture, well-drained soils in full sun to light shade. Plant stems will droop in too much shade. Plants tolerate poor soils. Avoid wet soils. New plants may be grown each year by planting seed indoors 6-8 weeks before last spring frost date or outdoors at the last spring frost date. In mild winter climates, seed may be planted outdoors in fall. Plants may reseed in the garden. Deadheading spent flower heads will limit self-seeding, but in the process removes from the garden seeds that are loved by birds. Taller plants may need staking or other support.


Taller varieties tend to flop once they reach 2.5 to 3 feet, so they may require staking. The plants will flower abundantly in well-drained, ordinary garden soil. Although they tolerate dry conditions, they need plenty of water in hot, dry weather to ensure continued blooming. Bachelor's buttons can be grown in containers for winter flowering.

Practical use

Bachelor's buttons flower from late June through August if deadheaded. They are excellent for cutting and drying.
