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. These amazing poppies are an annual herb growing 2-3 feet tall with gorgeous flowers that vary in color from reddish purple to white, from lavender and pink to deep red and can be single or double. All produce edible poppy seed. You can also find bread poppy seed in bird seed mixes, you'll find it in little jars in the grocery store baking section and it's the seed found in poppy seed salad dressing and the seed that is ground and added to sauces for flavoring and thickening. The bread poppy is a cool season annual that is sown early in spring, is hardy to USDA Hardiness Zone 7 and is not frost tender. 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.
