Even though corn poppy is an annual, it will regrow strongly the following year if seed falls on bare ground. Will grow in all regions of North America in full sun. Red poppy grows best in loose soil, not heavy clay. It also prefers a neutral pH of around 7, but it is adaptable. Seed is very tiny so it should not be covered by soil or other matter. May be sown in spring or fall after frost. Fall seeding produces very early spring blooms.
