Sisyrinchium langloisii, commonly known as Roadside Blue-eyed Grass, is a perennial herb native to prairies, open woodlands, and meadows in the southern United States, especially Texas and Louisiana. It typically grows to a height of 6-12 inches (15-30 cm) and forms dense clumps of narrow, grass-like leaves. The plant produces bright blue, star-shaped flowers with yellow centers that bloom profusely in the spring and early summer, adding a splash of color to the landscape. The flowers are quite showy and attract pollinators such as bees and butterflies.

Roadside Blue-eyed Grass is valued for its low maintenance and ease of growth, making it an excellent choice for naturalistic plantings, borders, rock gardens, and as a ground cover in sunny to partly shaded areas. It thrives in moist, well-drained soils but can tolerate periods of drought once established. While it prefers full sun to partial shade, it will bloom less profusely in shadier conditions. This species is not commonly afflicted by serious pests or diseases, but overwatering or poor drainage can lead to root rot. It is not known to be invasive and generally stays within its bounds without aggressive spreading.CC BY-SA 4.0
