ENGLISH ESSAY ON THE SCARLET LETTER PLEASE HELP!!!?

i don't really understand what this prompt is asking can somebody please help! : In the beginning of the scarlet letter, Hawthorne symbolically plucks a rose from the wild rose-bush in front of the prison door and presents it to the reader, stating that "it may serve, let us hope, to symbolize some sweet moral blossom, that may be found along the track, or relieve the darkening close of a tale of human frailty and sorrow." In a well-organized essay, discuss what "sweet moral blossom" may be extracted from the novel, and how this moral affects your understanding of the work as a whole.
