Sisyrinchium micranthum, commonly known as annual blue-eyed grass, blue pigroot, fairy stars, and striped rush-leaf, is a wildflower.

[2][3] It is a grass-like species in the iris family, Iridaceae.

It is native to Mexico, Central America, and South America and widely naturalized elsewhere.

Often the flowers are white with blue to purple centers, but may bloom in other colors such as yellow, pink, or violet.

[5] In much of its range, especially the southeastern United States, this species was known by the synonym Sisyrinchium rosulatum.
