Traditional uses

Despite the common name, this is no grass at all, it is a petite member of the iris family that Indigenous peoples and early botanists alike found easy to overlook among true meadow grasses until its sky blue stars opened each morning. Some related Sisyrinchium species carried a modest place in Indigenous folk practice in scattered corners of eastern North America, but the historical record for Sisyrinchium atlanticum itself is thin and inconsistent. Its real legacy has always been in the meadow rather than the medicine chest, a small bright thread woven through wet prairies and coastal grasslands for generations of foragers and flower gatherers to notice and admire.

Did you know?

The genus name Sisyrinchium comes from an old Greek word meaning pig snout, a nod to an ancient belief that pigs liked to root up the bulbs of a similar plant.

Safety

Blue-eyed grass has no established history of safe internal use, so it's best enjoyed as a garden and meadow plant rather than eaten.
