Germinating Iris versicolor Seeds
Blue Flag iris seeds require cold-moist stratification for 2 months at 4°C, followed by exposure to light when being sown in order to germinate successfully. Soaking your seeds for 1 week prior to stratification will improve germination. Change the water daily. After stratification, sow the seeds so they are barely covered and keep the growing media moist. Keep in a very bright location with a consistent temperature of 20ºC for the best germination. Germination can take up to 3 months. Transplant once seedlings have 3-4 leaves. Harden off seedlings before moving them outdoors if they were grown inside.
See All About Seed Dormancy & Stratification to learn more about successfully germinating and growing plants from seed.
