These easy-to-grow annuals are often called 'Cornflowers'. Seeds may be sown directly in the garden in April or May, when the soil becomes workable or in the fall before the ground freezes. For an abundance of brightly coloured blooms all summer long, sow seed successively every few weeks. Bachelor's Buttons prefer full sun to partial shade and will even succeed in less-than-ideal soil conditions. Makes great cut or dried flowers.
