In the poem *"The Trees"* by Adrienne Rich, the central idea is the symbolism of trees as agents of change and freedom. The poem describes the growth of trees in a confined space, representing the desire for freedom, transformation, and the breaking of constraints. The trees symbolize a yearning for a better, more liberated existence. The poem reflects themes of growth, renewal, and the need to break free from oppressive forces. Through the imagery of trees, Rich highlights the power of nature as a metaphor for personal and social change.
