Stout Blue-Eyed Grass (Sisyrinchium angustifolium) is a perennial forb native to Eastern and Central US states (such as Virginia, Ohio, Illinois, and Missouri) that can thrive in USDA Zones 4–9. Reaching a mature height of 8–20 inches with an upright clumping growth habit, it features flat, grass-like green leaves and produces small, violet-blue, star-shaped flowers with bright yellow centers. It thrives in damp meadows, open woods, and shoreline margins and is ideal for wet prairie restoration, rain swale stabilization, and native bee forage.
Short native perennial with dark blue flowers and a yellow eye, blooming March to July. Rhizomatous, preferring sandy to clay soils in moist grassy meadows and open woodlands; up to 8,000 ft. elevation. Tolerant of salty conditions, seasonal flooding and foot traffic. Use in meadow restoration and to colonize open garden areas.
