Sow the seeds in a suitable, well-drained growing medium and follow the supplier's instructions for sowing depth and pretreatment. Some iris seeds benefit from cold stratification to help overcome dormancy. Germination can be slow and variable, so maintain suitable moisture and allow adequate time for seedlings to emerge.
Iris germanica plants grown from seed often need several growing seasons to mature enough to flower. The exact time depends on the seed variety, growing conditions, and seedling development. Seed-grown plants may also produce different flower colors or characteristics from the parent plant.
Most bearded iris varieties flower best in full sun, generally receiving at least six hours of direct sunlight daily. They also need well-drained soil because excessive moisture can cause rhizome problems. In very hot climates, some afternoon shade may help reduce heat stress.
