Bachelor's button, cornflower

Centaurea cyanus

Plants of Home and Garden

Sow directly outside in fall for spring germination, or around last frost. Cover with soil, as dark is needed for germination. Plant does best in full sun and average, sandy soil. Tolerant drier conditions, poor soils, exposed locations. Some dwarf forms grown as pot plants. Annual; self-sows well

Note that the similar, but perennial, Centaurea montana is grown in the same manner; it may also be divided in spring. Hardy zones 3-8
