About Blue-eyed Grass: Sisyrinchium genus
Blue-eyed Grass is the common name for the genus Sisyrinchium, which is composed of five species in Kansas. Three of these species are quite rare in the state. The genus is composed of about 150 species, all found in the New World, and about 40 species in the United States. Sisyrinchium is a challenging genus due to slight morphological differences among species.
The Blue-eyed Grasses are not grasses but members of the Iris (Iridaceae) family. All have grass-like foliage, and some have blue flowers, while others have flowers that range in color from blue to white. Their fruits are spherical capsules.
The spring flowering Blue-eyed Grasses prefer well-drained soils. They can be propagated by seed or divisions. Their abundant blooms, attractive foliage, and diminutive habit make them handsome additions to gardens.
Narrow-leaf Blue-eyed Grass: Sisyrinchium angustifolium
Narrow-leaf Blue-eyed Grass is native to the extreme eastern part of Kansas. It may grow to 12 inches tall and is usually found in moist woodlands and sometimes prairies. The flowers may be light blue, violet, or occasionally white. The foliage is dark green rather than the blue-green color seen in the more common S. campestre. The individual flowers are found on branching stems.
Prairie Blue-eyed Grass: Sisyrinchium campestre
Prairie Blue-eyed Grass is native to the eastern half of Kansas. Pale blue to white flowers with yellow centers appear in spring.

It's also known as Prairie white-eyed Grass.
