The seeds of Packera hesperia need cold stratification or exposure to low temperature to germinate. This process helps break the seed coat, and allows the plant to absorb water needed for germination. The seeds can be started indoors in late winter or directly sown in the garden after danger of frost has passed in the spring. Cover the seeds lightly with soil, and keep the soil moist but not wet until germination occurs.
Division Propagation
Division propagation is best done in the spring when the plant is actively growing. Dig up the plant, and carefully separate the roots into smaller pieces with a clean and sharp knife or garden shears.
