The Wild Iris is a collection of poetry by Louise Glück. The poems are set in a garden and feature the voices of plants, flowers, God, and the poet herself. Glück wrestles with her religious agnosticism, while the plants in the garden bloom in the spring and begin to die in the late summer. God expresses his disappointment with his creations, but ultimately demonstrates that he is always present. The collection considers themes related to mortality, suffering, and the natural world, among others.
