Edita Morris was born in Örebro in Sweden. Her parents were Reinhold Toll, an agronomist who had published books on dairy and cattle farming, and Alma Prom-Möller. The Toll family was well-known in Sweden. Her grandfather was a general. She grew up in Stockholm as the youngest of four sisters. When she was still a child her father left the family and emigrated to England.

She married in 1925 the journalist and writer Ira Victor Morris (1903-1972), whose father, Ira Nelson Morris, served as the U.S. envoy in Stockholm. He gave them a manor house in the small village of Nesles-la-Gilberde, 60 kilometers outside Paris. Ira and Edita had several homes and traveled widely throughout the world. They spent the Second World War years in the United States. They were political activists committed to nuclear disarmament and opposed to many U.S policies of the Cold War.

Edita started her literary career with short stories published in the Atlantic Monthly, Harper's Bazaar and other publications. In 1943 she published her first novel, My darling from the Lions. During the 1930s and until his death in 1943 in New York she shared much of her life with the Swedish painter Nils von Dardel. She figures on many of his paintings from 1930 onwards.

She is mostly known for her novel The Flowers of Hiroshima (1959). The novel was partly influenced by the experiences of her son, Ivan Morris, later a distinguished japanologist, as an intelligence officer in the U.S. Navy visiting Hiroshima immediately after the dropping of the atomic bomb on the city. The book has been translated into 39 languages. In 1978 she published Straitjacket: autobiography which was followed in 1983 by a second volume, Seventy Years' War, published in Swedish only under the title Sjuttioåriga kriget.

With her husband, who came from a wealthy family background, she founded a rest house in Hiroshima for victims of the bomb. After her death, the Edita and Ira Morris Hiroshima Foundation for Peace and Culture, usually known as the Hiroshima Foundation, was established. The purpose of the Foundation is to promote peace by supporting efforts in the cultural sphere to favor peace and reconciliation. The Foundation presents awards to women and men who contribute, in a cultural field, to fostering dialogue, understanding and peace in conflict areas. Edita died in Paris in 1988. She is buried, with her husband and her son, in the village of Nesles.
