Propagation of roots, buds and seeds
In the field, asexual propagation is the main one. The underground stem is brittle and easy to be broken, and new plants can grow from each broken body with nodes. Seedling emerges in spring in North China, flowering in summer, and fruiting from in autumn. The seedlings appear in spring in the Yangtze River Basin, and the flowering period is in spring.
