Iris douglasiana is an evergreen perennial with an upright, clumping habit and featuring glossy, dark green, sword-shaped leaves and flowers that usually are violet-purple, but can also emerge lavender, blue, pale cream, yellow, or white. Uses include dry shade plantings under oaks, groundcover, borders, erosion control. Excellent for coastal landscapes. Prefers light or part shade inland, can take more sun right on the coast. It is best in well-drained, acidic to neutral soils rich in organic matter, but adapts to clay. Low to medium water use. Drought-tolerant near the coast; appreciates regular or occasional summer water in hot inland landscapes. Deer-resistant. Resistant to Verticillium wilt. Fire-resistant. Cold hardy to 10°F.
