Grimké wrote essays, short stories and poems which were published in "The Crisis," the newspaper of the NAACP, edited by W. E. B. Du Bois, and "Opportunity." They were also collected in anthologies of the Harlem Renaissance: "The New Negro", "Caroling Dusk", and "Negro Poets and Their Poems". Her more well-known poems include "The Eyes of My Regret", "At April", "Trees", and "The Closing Door". While living in Washington, DC, she was included among the figures of the Harlem Renaissance, as her work was published in its journals and she became connected to figures in its circle. Some critics place her in the period before the Renaissance. During that time, she counted the poet Georgia Douglas Johnson as one of her friends.
