Background

Perennial flowers are perennial herbaceous plants that can survive for 2 years or more and flower each year after maturity. In garden cultivation, this term is also used to refer to subshrubes whose base is wood. In general, perennial flowers refer to flowers that are capable of "hibernation", and the overground parts of the flowers can germinate, grow, blossom and bear seeds in the spring of the next year. The flower has the advantages of simple and convenient propagation and management, can bloom for many years after being planted for one year, and is a plant material which is extremely suitable for greening and beautifying cities and towns. The underground part of the plant is used for storing flowers which live through the winter without forming enlarged spherical or blocky roots, still can sprout and bloom in the next spring and last for years. Most of them belong to the ecotype in cold regions. Can be divided into two categories of cold resistance and cold resistance. The former can be planted in open field, the latter needs greenhouse cultivation. The method mainly comprises the step of plant division propagation, which is generally carried out in a dormant period. The species with few new buds can be propagated by cutting, grafting and other methods.
