The black seeds of this poppy are used to flavor bagels and other pastries. It also has attractive flowers and interesting seed pods, and can be used in dried flower arrangements. The bread poppy is a cool season annual that is sown early in spring. The plants flower and die quickly and are often gone by mid summer. Seeds left in the garden will germinate next spring, so even though it is an annual, it usually appears in the garden every year as long as the seed heads are allowed to ripen. You can find bread poppy in the National Herb Garden.
