Sisyrinchium angustifolium (Blue-Eyed Grass)
Blue-Eyed Grass, native to the eastern United States and a member of the Iris family , is one of the most charming wildflowers I know. The grass-like foliage and small blue (sometimes purple or white), star-shaped flowers with yellow centers, or "eyes," are clump-forming. This spring-blooming perennial native is ideal for edging walkways and rock gardens, but its grass-like foliage can sometimes fool you, so be vigilant when weeding. Blue-Eyed Grass grows to about eight inches in sun and well-drained soil. Zones 4-9. Quarts.
