The rose-bush in front of the prison represented hope for those entering the prison, and stood out as something beautiful within the ugliness of Puritan society, both metaphorically as a symbol of hope and literally within the weeds in front of the prison.

However, the prison behind it represented the strictness and rigidness of Puritan society, as well as the theocracy that dominated its social system and government resulting in dull and controlled lives.
During the early parts of the book, Hester's scarlet letter was a symbol of shame, ignominy, and disgrace within Puritan society, as well as the sin that Hester committed, and was scorned as a result.
"But in their great mercy and tenderness of heart, they have doomed Mistress Prynne to...wear a mark of shame upon her bosom."
"Do you see that woman with the embroidered badge? It is our Hester... who is so kind to the poor, helpful to the sick, so comfortable to the afflicted!"
However, later on in the story, the scarlet letter and Hester come to represent hope, kindness, helpfulness, and tenderness. People began to interpret it as standing for "able" rather than "adulterer".
"Hasten, Pearl; or I shall be angry with thee! Leap across the brook, naughty child, and run hither! Else I must come to thee!"
Throughout the series of events within the forest, the brook represents a boundary between escaping to freedom and being limited by society; a boundary between 2 worlds that Pearl would not cross unless Hester reapplied her letter.
Why is the minister with my mother? And where is her letter?
