Iris douglasiana - Douglas Iris

Iris douglasiana - Douglas Iris

Pot size: 4" deep

Douglas Iris is a knee-high perennial with rhizomes that spread slowly into a 2 to 4 ft wide clump. The flowers arise on a 1 to 2 ft high stem, medium purple and three inches wide. Douglas Iris is native from Santa Barbara to Oregon and likes full sun near coast, afternoon shade inland, some summer water. Fast growing near the coast, but slow inland. This iris prefers richer soils, such as clay, with organic matter, and is not happy when the winters are cold (snow) and the soil gravelly. Does fabulous in the runoff of buildings. That little ditch that the water runs down the street in is a perfect spot for Iris.
