This common springtime wildflower can be found in wet grassy flatwoods, wet prairies & fields, moist roadsides and stream banks throughout nearly all of Florida. The range extends into Texas, Louisiana, Arkansas & Missouri, and all states east of the Mississippi River except West Virginia. Also occurs in Nova Scotia.
Eastern blue-eyed grass has grass-like leaves shorter than the winged flower stems and blooms of up to about an inch across appearing mostly in the spring and early summer. The flowers have six tepals that are pale blue to violet with yellow bases and often artisate (with an awn or bristle tip).
Some sources list Sisyrinchium angustifolium and S. atlanticum as separate species while others have them as synonyms for the same species.
