Sisyrinchium idahoense, or Idaho blue-eyed grass,[2] is a perennial that is native to the Western United States and Canada. It is not a true grass, but is related to the Iris in the Iridaceae family.[3]


Sisyrinchium idahoense is found in generally moist grassy areas and open woodlands, and by stream banks, below 2,400 metres (7,900 ft). It grows 6-18 in tall with narrow grass-like leaves. The flower is usually a deep bluish purple to blue-violet, or pale blue, rarely white, and yellow-throated.
