Explain - " the flower of cities from sinking and withering faint."

Dear student,

The answer for your question is:

The peasants from the countryside desire for some city money. They hope that the people from city would stop nearby and buy something from them. The money raised from such deals will help them to earn their living. For the poor people who are standing at   roadside money is essential for growth and survival. It boosts the growth of the city and people residing there. Here flower signifies prosperity or growth. As the flower is the crowning glory of a plant, growth is the flower of a city.
                      
Hope it helps.

Regards.
