Perennial; Gorgeous, bold color! Large red-orange flowers bloom in summer Poppy seeds require a cool period of 2-4 weeks to break dormancy, and some gardeners choose to cold stratify their seeds. Boasting large and intensely colored blooms, this Oriental Poppy is easy to grow and sun-loving. A double layer of orange-scarlet petals are each dabbed with black giving this bloom a touch of the exotic. A perennial poppy that does well in cooler climates.
