Days to Germination:7-14 days
Centaurea cyanus. It is best to direct-sow Bachelor’s Buttons in well-draining, loamy soil in full sun as soon as the ground can be worked. Plant 1⁄2" deep and tamp down well since they require darkness for optimal germination. Keep uniformly moist until the seedlings emerge, up to 2 weeks after sowing. Or sow indoors 4 weeks before planting outside, in a good seed-starting medium at about 60° to 70°F. Provide even moisture, strong light and good ventilation. Prior to transplanting, acclimate the seedlings by gradually exposing them to outside conditions for 1 to 2 weeks. Thin or transplant 6" to 12" apart in the garden. Weed and keep well-watered until established. Drought tolerant, water moderately once established. Summer flowering. Height: 3'.
