The yellowleaf iris, Iris chrysophylla, is a wildflower which ranges from midwestern and southern Oregon west of the Cascades and south to the crest of the Siskiyou Mountains in northern California. The yellowleaf iris grows up to 5,500 feet (1,700 m) elevation, most commonly in open, coniferous forests.


This herbaceous perennial grows from compact, dark brown and slender rhizomes. The leaves are linear, finely ribbed, and light green, 25–50 cm long, and may be reddish colored at the base. The flowering stems are simple, solid, and slender, 3–20 cm. The flowers are cream to pale yellow, with dark golden to reddish-brown or lavender veins. The plant flowers from April through June.
