"A Poison Tree" is a poem by English poet William Blake, first published in his Songs of Experience in 1794. In deceptively simple language with an almost nursery-rhyme quality, the speaker of the poem details two different approaches to anger. In the first, openly talking about anger is presented as a way of moving past it. In the second, the speaker outlines the danger of keeping anger within. The poem uses an extended metaphor to describe the speaker's anger as growing into a tree that bears poisonous apples. The speaker's enemy then eats an apple from the tree and dies. The poem is generally interpreted as an allegory for the danger of bottling up emotions, and how doing so leads to a cycle of negativity and even violence.
