Iris douglasiana (Douglas Iris)

Iris douglasiana (Douglas Iris) is a slowly spreading rhizomatous evergreen perennial forming clumps of sword-shaped, arching, dark green leaves. Branched stems rise from the clumps in spring, each of them boasting usually blue flowers, 3 in. across (7 cm), although the flowers can be variable in color, ranging from pale cream to yellow to reddish purple. Very handsome in and out of bloom, Douglas Iris truly enjoys meadow settings. Perfect for tucking into rock gardens or to edge woodland borders. Native to coastal areas from Santa Barbara into Oregon, Douglas Iris adds color to shady garden spots. Growing in full sun along the immediate coast, it is also found growing in the light shade of open woods and forest edges.

• 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 seed (early fall) or rhizome divisions (late fall or early spring).
• Deer resistant.
• All parts may cause discomfort if ingested. Wear gloves and other protective equipment when handling.
• Toxic to dogs, toxic to cats, toxic to horses.
• Native from the coastal regions of Northern and Central California and southern Oregon.
