Yellow Douglas Iris, Iris Douglasiana Yellow

The Yellow Douglas Iris (Iris douglasiana 'Yellow') features robust 2 to 3-foot-wide clumps of arching, dark green sword-shaped leaves. Blooming from spring to early summer, its 3 to 4-inch sun-yellow flowers with orange to orange-brown veins rise on 1 to 2-foot stems. This hardy plant thrives in diverse conditions—from dry, shaded oak groves to coastal full sun—and adapts well to various soils, especially richer, clay-based ones with organic matter. Once established, it requires minimal watering, making it an excellent choice for sustainable landscaping and ground cover in mixed light environments.
