Sisyrinchium angustifolium, commonly known as narrow-leaf blue-eyed-grass, [3] is a herbaceous perennial growing from rhizomes, native to the eastern United States, stretching as far west as Texas and Kansas, where it is the most common blue-eyed grass. It is commonly cultivated as an ornamental.
Height: 15–50 cm (6–20 in). Stem: broadly winged, 2–4 mm (1⁄16–3⁄16 in) wide, usually branched. Leaves: 2–6 mm (1⁄16–1⁄4 in) wide. Tepals: 6, blue, [4] 7–10 mm (1⁄4–3⁄8 in), each tipped with a sharp point, veined, and darkening toward central yellow patch.
S. angustifolium is most commonly found in habitats such as woodlands, meadows, and sandhill swales. [5]
This species possesses an intermediate shade tolerance and is adapted to both fine and medium textured soils. [6]
S. angustifolium tends to flower from January to May, with peak inflorescence occurring in the spring, around April. [7]
