Breadseed poppy. Papaver somniferum is the largest annual poppy, reaching more than 3 feet tall. In summer, it bears flowers in shades of pink, lilac, mauve, red, or white, followed by large seed pods that are good for dried arrangements. Use the dried seeds in baking, too. Papaver rhoeas grows up to 3 feet tall and 1 foot wide. In summer, it bears brilliant orange-red flowers, sometimes marked with a black base on the petals. It is also called field poppy, a reference to its tendency to naturalize in open fields. Papaver croceum is a short-lived perennial usually grown as an annual.
