white Douglas iris
A dependable and floriferous selection of the native Douglas iris, with springtime flowers that are pure white with yellow markings on the falls. Broad shiny blades are mostly evergreen and grow a foot or more tall and form compact clumps. Plant in sun to part shade, particularly in hot inland areas, with moderate to little summer water. Prefers good drainage but will grow well on clay soils provided they are mounded up. Too much summer water on heavy soils will prove fatal. Deer resistant.
