Iris douglasiana, the Douglas iris, is a common wildflower of the coastal regions of Northern and Central California and southern Oregon in the United States.[2] It grows mainly at lower elevations, below 100 meters 330 ft, though it is occasionally found at heights of up to 1,000 meters 3,300 ft. It is most common in grasslands near the coast; it is regarded as a noxious weed in pastures, because it forms clumps that inhibit other vegetation, and its leaves are bitter and unpalatable to cattle.
