Iris innominata
Del Norte iris is a beautiful Pacific Coast native iris prized for its variable yellow, lavender, and gold flowers that appear in late spring. It prefers part shade with humus-rich, well-drained, slightly acidic soil and consistent moisture during its active growing period. Once established it is relatively tough, but it benefits from light grooming and occasional division every few years to maintain vigor.
