One of the most easily grown of the California native iris, this species has been used extensively in the Pacific Coast Hybrids. It forms compact clumps with evergreen, arching leaves of variable height, usually dark green and shiny on one surface and light green and duller on the other. The spring flowers generally range in color from pale lavender to deep violet, with narrower petals than on some of the Pacifica hybrids. Sun or part shade, reasonably well drained soil, moderate to little watering when established.
