 Iris chrysophylla Howell yellowleaf iris

Known as a northwest grass iris, this wildflower is found in concentrations throughout Oregon and northern California in USDA zone 6-9 areas.

The grassy leaves and stem are long but are often bent over giving the plant an overall shorter appearance.

The flower is cream colored with a yellow strip down the centered, which is surrounded by dark purplish veins.

These irises will spread by rhizomes, eventually forming clumps.

Grow them in an open area receiving moderate water and sunshine.

These flowers are especially appropriate for the grassy meadow and open woodland.
