One of 11 species of native iris collectively known as Pacific Coast iris, Douglas iris, Iris douglasiana, is native to the Oregon and California coasts. It grows most often in grasslands, where it is tolerant of full sun and poor soil. It is never found more that 2 miles from the coast.

Douglas iris grows from 12"-24" tall and forms clumps from 24"-36" wide. It has tough, spikey evergreen foliage. Its flowers vary from pale lavender to deep purple and are produced from April through June, attracting bees and butterflies. Since it is a vigorous grower, it is best used in natural areas of the garden. Although it is evergreen, its appearance benefits from having the foliage cut back in late winter or early spring.

Fibers taken from the foliage of Douglas iris were used by Native Americans to fashion fishing nets and snares to capture small game. Although the fresh rhizomes are toxic, indigenous people used the dried rhizomes to heal wounds.
