Summary

Sisyrinchium angustifolium, commonly known as Narrowleaf Blue-eyed Grass, is a herbaceous perennial native to moist meadows, shorelines, and open woodlands across the Eastern and South Central USA, as well as parts of Southern Canada. It is the most common blue-eyed grass in the eastern United States. This plant typically forms clumps reaching 6-12 inches in height and width, with narrow, grass-like leaves. The small, star-shaped flowers are predominantly blue or purple with a yellow center, blooming profusely in late spring to early summer and adding a splash of color to the landscape.

Narrowleaf Blue-eyed Grass is valued for its low maintenance and the charming, delicate flowers that attract pollinators such as bees and butterflies. It is used in rain gardens, as a border plant, or in naturalized areas where its clumping habit can help control erosion. It prefers consistently moist soils but can tolerate periods of drought once established. It thrives in full sun but can also handle part shade. While generally pest-free, it can suffer from rust or leaf spot in overly wet conditions.CC BY-SA 4.0
