  First discovered in a garden in Northern France, the flowers of this beautiful variety are pure white with a green hood. These appear on the tall, upright flowerspikes throughout the summer above large and handsome foliage. A wonderful addition to the border where they will add vertical interest to the planting scheme. They are easy to grow and relatively undemanding in well-drained soils.
