About Narrowleaf Blue-eyed Grass
Blue-Eyed Grass (Sisyrinchium angustifolium) is a native perennial of eastern North America and Florida in the iris family, forming neat tufts of narrow, flat, grass-like leaves and bearing small, star-shaped blue-violet flowers with yellow centers in spring and early summer. Despite its delicate appearance, it is a tough, adaptable native for moist to average garden soils. Starting at $9.95.

Care essentials
Blue-eyed grass performs best in full sun to part shade; adequate light is needed for consistent flowering through spring and into summer.
Prefers consistently moist to average soils; naturally found along moist meadow edges and swale margins in Florida — do not let it dry out completely during the growing season.
Grows in sandy to loamy moist acidic soils; little fertilizer required. Divide clumps every 2-3 years after bloom to maintain vigor, and allow self-seeding for naturalistic plantings.
