Sisyrinchium idahoense
Sisyrinchium idahoense
Idaho blue-eyed grass is a charming, grass-like native perennial from the iris family that produces small, vivid blue-violet flowers with yellow centers in late spring and early summer. It grows best in moist, well-drained soils with partial to full sun and is an excellent addition to rain gardens, pond margins, or naturalized borders. Very low maintenance once established, it self-seeds gently to form attractive clumps over time.
