Douglas Iris | Iris douglasiana seeds
Iris douglasiana is a perennial species of iris known by the common name Douglas Iris. Native to coastal California and southern Oregon, it is a hallmark of coastal prairies, bluffs, and open woodlands, often thriving where ocean fog provides additional summer moisture. This hardy and attractive plant is well-suited to gardens, where it can naturalize easily and form striking clumps of foliage and blooms.
The plant produces evergreen, sword-shaped leaves that reach up to 2 feet long. In spring, it sends up flower stalks bearing elegant blossoms, typically in shades of purple to deep violet, though occasionally white, cream, or pale lavender forms occur. Each flower has gracefully spreading falls with darker veining and a central yellow or cream signal. The flowers attract native pollinators, including bees and butterflies, and provide a bold splash of color from March through May.
Douglas Iris grows best in full sun along the coast and partial shade inland. It prefers well-draining soils, tolerates clay, and requires little water once established, though it benefits from some summer irrigation in drier areas. An excellent choice for native plant gardens, borders, and naturalized plantings.
