Native to far northern California and into western Oregon, this uncommon iris grows in fast draining soils in open forests and woodlands. A small scale iris, usually under 12 inches tall in bloom, spreads slowly from slender rhizomes. The delicate blossoms flower in the spring and can vary in color from white to cream to yellow, with a central yellow splash and prominent dark venation. Grow in sun to light shade with occasional to little watering. Visited by bees and hummingbirds. Deer resistant.
