Conditions and Care

As a cool-season flower, Bachelor's Button (Cornflower) does its best growing in the cooler weather of spring and fall and tends to bolt or turn bitter in summer heat. It is frost hardy and can shrug off light freezes, so it can stay in the ground later into the season than tender crops.

Bachelor's Button (Cornflower) needs full sun — give it at least six hours of direct light a day for the best growth and flavor. Sow seed about 0.25 inches deep — small seed is sown shallow and barely covered, then keep the soil evenly moist until seedlings establish.

Bachelor's Button (Cornflower) belongs to the Asteraceae family; rotating where you grow members of this family each year helps limit the build-up of soil-borne pests and disease. Bachelor's Button (Cornflower) is generally grown as a single planting each season rather than succession sown.
