Cultural Significance
Despite the misleading common name, Blue-Eyed Grass is not a grass but a beloved native iris relative found across North America. The plant's charming star-shaped flowers with bright yellow centers (the "eye") open in the morning and close by afternoon, creating a magical daily cycle. The flowers provide crucial early-season pollen and nectar for native bees, especially halictid bees and green metallic bees. Native Americans recognized various Sisyrinchium species and used them in natural landscapes. The plant represents the subtle beauty of native wildflowers and the importance of preserving native meadow ecosystems.Shop Our Floral Collection
