Answer:
Literary devices which are used in this poem are:
1. Personification: the rose that walks, breathes and dreams.
2. Metaphor: the rose actually represents a metaphor for a poet, who describes himself and his life, as he managed to leave his bad past behind him and start a new life in the present.
3. Alliteration: Crack in the concrete and Long live
4. Symbols: the author uses a rose to describe his life and his path from "bad" to "good guy."
Explanation:
Personification is a literary device that consists of attributing human characteristics to nonhuman things and objects.
The metaphor represents an implicit comparison between two or more things that are not related, but they share some common characteristics.
Alliteration is the repetition of the same letter or sound within a series of words.
A symbol is a literary device that uses an object to describe some concept or thing beyond its literal meaning.
