Planting & Care

Sow Blue Bachelor's Button seeds directly in the garden after the last frost, or start indoors 4–6 weeks before transplanting. Press seeds lightly into the soil surface, as they need light to germinate. Keep the soil consistently moist until seedlings emerge, which typically takes 7–14 days. Thin seedlings to stand 6–12 inches apart to encourage good air circulation.

Once established, cornflowers are relatively low-maintenance. Water during extended dry periods, and deadhead spent blooms to prolong flowering. Avoid overly rich soil, which can lead to floppy growth. These plants self-sow readily, so allow some flowers to go to seed for a repeat display the following year.
