Sisyrinchium angustifolium

Sisyrinchium angustifolium Mill.

Narrowleaf Blue-eyed Grass, Narrow-leaf Blue-eyed-grass, Bermuda Blue-eyed Grass, Blue-eyed Grass

Iridaceae (Iris Family)

Synonym(s): Sisyrinchium bermudiana, Sisyrinchium graminoides

USDA Symbol: sian3

USDA Native Status: L48 (N), CAN (N)

The numerous, narrow, light-green leaves of this perennial form dense, tufted clumps which steadily grow with new foliage during the season. The flattened, leaf-like flowering stems may be up to 18 in. long and bear star-shaped flowers a few inches above the leaves. Several delicate, blue or blue-violet flowers with yellow centers in 2 broad bracts top a flat stem, generally only 1 flower at a time in bloom; stems taller than the clusters of narrow, sword-shaped leaves near base.

Although the plant is small and has grass-like leaves, the flowers have all the features of the Iris family. The various species are all much alike and separation is based on such characteristics as branching pattern and leaf length. Common Blue-eyed Grass (S. montanum) is also a widespread species, with slightly wider leaves, over 1/4" (6 mm), and unbranched stalks.
