Vegetative Growth
3-4 weeksPlants developing multiple stems, feathery foliage, and reaching 12-18 inches tall
Pinch back growing tips when plants are 6 inches tall to encourage bushier growth and more flowers. Minimal fertilizer needed.
Budding

Deadhead spent flowers regularly to encourage continuous blooming throughout the season. Cut flowers for arrangements; cutting extends bloom time.
Seed Production & End of Season
2-4 weeks until frost or heat stressFlowers fade and seed heads form; plants may self-sow if allowed to mature
Allow some flowers to go to seed for self-seeding next year, or deadhead all flowers to prevent excessive self-sowing. Plants decline as temperatures warm in summer.

Cornflowers are excellent cut flowers and dry well for arrangements—harvest for drying when fully open and hang upside down in a dry location.
