rhizomes that spread slowly into a 2 to 4 ft wide clump. The flowers
arise on a 1 to 2 ft high stem, are cream to light purple and three inches
wide. Douglas Iris is native from Santa Barbara to Oregon and likes

runoff of buildings. That little ditch that the water runs down the the
street in is a perfect place for Iris. No rain gutters, plant Douglas
Mix with bolders, Zauschneria
