This is about bamboo,,,,,u know bamboo？U can see many knots in the body of bamboo.The first sentence is：Bamboo has many knots. second sentence is:many many branches and leaves。 third sentence is：There is no blooms on bamboo。 Fourth one is ：Bamboo doesn't attract bees and butterflies。 Bamboo in Chinese culture is the symbol of noble qualities，，or that kind poeple。last sentence， Bamboo doesn't attract bees and butterflies。 This means Doesn't be such a swank。

一节复一节。这里是双关（pan）。"节"指竹节，亦指气节（高尚人格），这种双关的手法是中国咏物诗里常用的伎俩。 蜂，蝶，皆指攀附权势的小人。“不开花”指甘处贫贱，以远宵竖。

Thanks for saying
