Sisyrinchium pruinosum, the dotted blue-eyed grass, is a perennial plant in the family Iridaceae, native to the south-central United States.

There are also reports of the plant in California, but these appear to represent naturalizations.

[2] It is sometimes considered to be a synonym of Sisyrinchium langloisii.

[3] These plants are usually found in abundance and can be spectacular on warm, sunny days where they cover entire pastures with almost solid sheets of blue.

They are very beautiful used as borders in the wildflower garden.
