Sisyrinchium montanum

Sisyrinchium montanum, the blue-eyed-grass, American blue-eyed-grass, or strict blue-eyed grass, is a grass-like species of plant from the genus Sisyrinchium, native to northern North America from Newfoundland west to easternmost Alaska, and south to Pennsylvania in the east, and to New Mexico in the Rocky Mountains. It has also been introduced to parts of France, likely during the First World War.

It is very similar to S. angustifolium, with which it is sometimes combined.
