An elegant purplish-blue flower that can also be white or yellow. The Douglas Iris blooms in spring at altitudes under 1000 feet (300 meters).

Tough leaves grow in clumps. When on grasslands, the Douglas Iris clogs grass growth and thus makes them unpopular with ranchers. Cattle cannot eat these leaves.

This Douglas Iris blooms in spring, yet one flower remained in mid summer.

Indians used the outermost strands of fiber from this leaf's margins for weaving.

Its leaves are about 1 inch (2 centimeters) wide and the plant grows to only about 6-31 inches (15-80 centimeters) tall.

When the flower expires, it simply dries out. This plant was full of such dried out flowers.

At the very end, the flower turned completely black as if a burned cinder.
