It can be carried out in spring and autumn. The specific method is: the cut rhizome or bud, according to the size of plant in the nursery, and careful management can be. Most of the buds divided in autumn do not affect the flowering in the following spring; the smaller buds need to be growd for one year before flowering. The plant clusters growd for many years gradually extend outward and grow vigorously. Generally, the spacing between plants and rows is 25-30cm, with 2-3 buds per cluster and 5-6cm soil covering. Generally, it is planted once every 3-4 years. The seeds needed for sowing and propagation can germinate only after two low temperature periods. It takes 5-6 years for seedlings to blossom
