Most bamboos are perennial flowers, and only a few bamboos can bloom many times, that is, they can continue to grow after flowering and bloom every year, such as Phyllostachys pubescens. For the bamboo that blooms once, after flowering, the bamboo leaves turn yellow, partially or completely fall off, the bamboo stalks fade and turn yellow, and finally die. The flowering cycle of different bamboo species is different, even for the same bamboo species, the flowering cycle varies from place to place. For example, the common flowering cycle of Phyllostachys pubescens is generally 6 years, but according to records, the Phyllostachys pubescens forest in Shimen, Fenghua, Zhejiang Province has not blossomed for more than 2 years; The flowering period of Phyllostachys pubescens is long, generally about 12 years; However, Dendrocalamus latiflorus and Dendrocalamus latiflorus take about 32 years to bloom; The short-lived Phyllostachys pubescens can bloom once a year or so. It is worth mentioning that Phyllostachys pubescens is not produced in China. The flowering cycle of Phyllostachys pubescens is "willful" and irregular, depending on the growth environment. It can be seen that the flowering cycle of bamboos in China is generally longer.
There are two types of bamboo flowering. One is that all bamboo species bloom in pieces. Once this kind of bamboo species blooms, it will bloom in whole piece and cluster, and bamboo shoots will no longer bloom normally, and new branches and bamboo shoots will also bloom soon after they are drawn. The other type is sporadic flowering, that is, this kind of bamboo species usually has only one or two clusters or sporadic bamboo plants and small pieces of flowers in a certain area and time. In fact, many bamboo species belong to the whole flowering type, and only a few bamboo species are sporadic flowering types.
since bamboo can blossom, it will naturally think of the seeds after flowering. The flowering and fruiting of bamboo can be divided into two types: flowering and fruiting and flowering and not fruiting. Most bamboos, especially wild bamboos, are of flowering and fruiting type, while others are of flowering and fruiting type, for example, Phyllostachys pubescens and Phyllostachys praecox in Zhejiang, which have propagated their offspring through asexual propagation for a long time, resulting in "flashy" flowering.
