Iris douglasiana, the Douglas iris, is a common wildflower of the coastal regions of Northern and Central California and southern Oregon in the United States.[2] It grows mainly at lower elevations, below 100 meters (330 ft), though it is occasionally found at heights of up to 1,000 meters (3,300 ft). It is most common in grasslands near the coast.
Consumption may cause severe discomfort.[3]
This is a typical beardless iris of subgenus Limniris, series Californicae, growing from a rhizome that is typically less than a centimeter in diameter. Its leaves are about 2 centimeters (0.79 in) wide. The flowers, appearing from April to June, are usually a purplish-blue, though occasionally white or yellow flowers are found. Two or three flowers are found on each stem, which is of variable height, ranging from 15–80 centimeters (5.9–31.5 in) tall.
