Dormancy: Winter Height: 90 cm Culture: Part Sun to Light Shade Origin: United States This species iris, also know as Zebra Iris, Sweet Iris, or Dalmatian Iris, is a very old garden plant. Native to rocky areas of northern Italy and the Eastern Mediterranean (including Dalmatia, a province of Croatia, hence one of the common names), it was one of the primary species used in the development of the tall bearded iris. Its dried root (along with other species of Iris) is a source of orris root powder that was used medicinally or for its supposed magical and alchemical properties in medieval times, as well as a perfume and potpourri fixative for many centuries. It may take several years of drying for the root to fully develop its fragrance. Orris oil, derived from the fresh root, is used as a flavoring in soft drinks, candies and chewing gum.
