It is best to grow Eschscholzia members outdoors. When growing California poppies the seeds should be sown at about 6 mm in the autumn or after the last frost of spring. The seeds usually take about three weeks to germinate. They should be sown into an area that is sunny and has good drainage. California poppies like to grow in a soil that is average, so nothing special is required.
Once growing, Eschscholzia plants require watering in prolonged dry spells. Extended blooming of the poppies can be had by removing the flowering heads once they have finished flowering.
