Primary propagation methods for iberis include seed sowing, semi-hardwood cuttings, and division. Key factors for success are well-draining soil, moderate moisture, and bright but indirect light. Temperature should be kept warm, around 70-75°F for optimal growth. A special consideration for iberis is to not bury seeds too deep as they need light for germination. This species is easy to moderate to propagate. Challenges might include leggy seedlings or rot in overly moist conditions. For seed propagation: (1) Spread seeds on soil surface and lightly press in, (2) mist to keep moist, (3) keep in bright light without direct sun. For cuttings: (1) Take semi-hardwood cuttings in late summer, (2) dip in rooting hormone, (3) plant in well-draining soil mix, and (4) maintain high humidity and indirect light until roots develop. Division is best done in spring or autumn by carefully separating and replanting.
