Introduced in 1975 by the Santa Barbara Botanic Garden, Iris douglasiana ‘Canyon Snow’ (Douglas Iris) is a slowly spreading, rhizomatous evergreen perennial forming clumps of sword-shaped, bright shiny green leaves. Branched stems rise from the clumps in spring, each of them boasting large orchid-like flowers, 4-5 in. across (10-12 cm), adorned with brilliant yellow markings on each petal.

Very handsome in and out of bloom, Douglas Iris truly enjoys meadow settings. Perfect for tucking into rock gardens or to edge woodland borders.
- Winner of the prestigious Mitchell Award from the American Iris Society.
- Grows up to 1-2 ft. tall (30-60 cm) and 2-4 ft. wide (60-120 cm). Will self-sow and form large clumps.
- Performs best in full sun to part shade in heavy soils with organic matter. Water every 2-4 weeks in summer if not planted next to a creek or in a naturally wet area. More drought tolerant near the coast as a result of the cooler temperatures and fog.
- Increase by rhizome divisions (late fall or early spring).
- Deer resistant.
