Blue-eyed grass (Sisyrinchium graminoides)
Synonyms:  S. angustifolium
Genus:  Sisyrinchium
This clump forming, semi-evergreen, grass-like perennial blooms in summer, with a long succession of yellow-centered blue flowers. It grows to 20 inches high and 6 inches wide, and self-sows easily.
Noteworthy Characteristics:  Native to open woods, meadows, and prairies of North America, this adaptable wildflower tolerates a wide range of conditions and naturalizes easily. The spring or summer blossoms each open for just one day with the morning sun and close at dusk. Rarely do the blooms open on cloudy days. Blue-eyed grass is suitable for the edges of mixed borders.
Care:  Provide moderately fertile to poor, neutral to slightly alkaline soil in full sun. This plant can grow in sandy or clay soil, but it resents winter moisture.
Propagation:  Sow seed in a cold frame in fall or early spring or divide after flowering.
Problems:  Aphids, spider mites, rust.
