"Sisyrinchium bellum (Western Blue-eyed Grass, Californian Blue-eyed Grass) is the common blue-eyed grass of California and Oregon in and west of the Sierra Nevada, its range extending south into Baja California. In parts of its range, Western Blue-eyed Grass has previously been classified as Sisyrinchium eastwoodiae, S. greenei and S. hesperium, but these names are now considered synonyms.

Sisyrinchium bellum grows as a perennial plant in open places where there is some moisture, particularly grassy areas, though it can also be found in woodlands and at altitudes up to 2,400 metres (7,900 ft). Like other species of blue-eyed grasses that are locally dominant, it is generally known simply as "Blue-eyed Grass" within its natural range.

Sisyrinchium bellum prefers some moisture and good drainage, but will tolerate summer dryness. It can be propagated by seed, and it self-sows. It can also be propagated by division of its rhizomes, and the flower stems can be rooted. It is moderately hardy and will tolerate temperatures down to 20 degrees F; -12 degrees Celsius."
