Safety Overview
1.Sisyrinchium Angustifolium — Essential Profile
Sisyrinchium angustifolium, commonly known as Blue-eyed Grass, is an enchanting perennial herbaceous plant belonging to the Iridaceae, or Iris family. Despite its common name, it is not a true grass but rather a monocot characterized by its distinctive morphology. The plant forms dense, fan-like clumps of slender, grass-like leaves, typically growing 15-50 cm tall.
From this basal foliage emerge delicate, star-shaped flowers, usually bright blue to violet-purple, each featuring a prominent yellow center that gives rise to its 'golden eye' moniker. These charming blossoms typically appear from late spring through early summer, adding a splash of color to its native habitats. Sisyrinchium angustifolium is indigenous to eastern and central North America, extending into parts of Canada and some western states.
It thrives in a variety of moist, open environments, including meadows, prairies, open woodlands, along stream banks, and in disturbed areas. Its adaptability, attractive appearance, and low maintenance requirements make it a popular choice for rock gardens, borders, and naturalized landscapes, where it contributes to local biodiversity.
