Narrow-Leaved Blue-Eyed Grass

Sisyrinchium angustifolium

Despite its common name, Narrow-Leaved Blue-Eyed Grass is actually a delightful, grass-like member of the iris family (and not a grass at all!). It typically reaches about 6 to 12 inches in height and spreads slowly to form dense tufts. The plant sports slender, dark green leaves and from late spring to early summer, it blooms with star-shaped, bright blue flowers that open during the day and close at night. Each flower's center reveals a bright yellow eye that attracts a variety of pollinators such as bees and butterflies. Ideal for rock gardens, borders, and naturalized areas, it thrives in full sun to partial shade and prefers well-drained soil.

Ecological Benefits

Maintenance Tips

  • Drought-tolerant once established; water moderately until then, especially in hot, dry conditions.
  • Deadhead spent flowers to promote a longer blooming period and prevent self-seeding.
  • Prefers well-drained, moderately fertile soil but is quite adaptable to poorer soils.
  • Divide clumps in early spring every few years to rejuvenate and spread the plants.
  • Minimal care required; monitor for common garden pests and manage as necessary.
