Direct sow in early fall, sowing the seed just below the surface of the soil. For spring planting, mix the seed with moist sand and store it in the refrigerator for 60 days before direct sowing after the last frost. This process is called cold stratification. Plant in fertile, moist, well-drained soil and full sun or partial shade; this flower appreciates being shielded from the midday sun. Flowers planted from seed will bloom in their second year of growth. After blooming, the foliage will die off. Established plants can be divided, though they will self sow readily; volunteer plants can easily be transplanted. You will receive 100+ seeds as I always throw in extra.
Either pick up or I will mail them out in a regular stamped envelope at no extra cost.
