How to Plant a Bachelor Button From Seed
Bachelor button, or Centaurea cyanus, is also known as the cornflower. Mature plants are drought tolerant, undemanding and attractive to butterflies. Long-lasting flowers bloom from June to August and perform well as cut stems. Bachelor buttons are readily started from seed sown directly into the garden after all danger of frost has passed for your area.

Choose a well-draining site in full sun for your bachelor buttons. Cultivate the soil several inches deep and incorporate organic material such as compost, peat moss or well-rotted manure.
Sow bachelor button seeds directly into your prepared site. Space them about 2 to 4 inches apart and cover with ¼ to ½ inch soil. Bachelor buttons need darkness for successful germination.
Water the seeds thoroughly, moistening the soil evenly. Don’t let the seed bed dry out while bachelor buttons are germinating, but don’t allow the soil to become soggy or waterlogged, either. Seeds will germinate in about seven to 15 days.
Continue to water until seedlings sprout and develop several true leaves. Once established, they’ll be drought tolerant and probably won’t require anymore watering from you. Thin them to about 18 inches apart.
Feed bachelor buttons a good all-purpose fertilizer monthly throughout the growing season. Follow the packaging instructions carefully.
Water established bachelor button plants only if leaves or blooms appear wilted.
