Sisyrinchium angustifolium

Blue-Eyed Grass

Sisyrinchium angustifolium forms upright clumps of narrow, grass like green leaves that emerge in tidy fans and create a fine textured presence through the growing season. In late spring to early summer, slender stems carry small star shaped flowers in clear violet blue, each bloom centered with a bright golden eye and opening in succession above the foliage.

Native to eastern North America, the species grows naturally in open meadows and grassy clearings.

Design tip

Summer flowers carry the middle of the season, so place it where the bed needs color once spring bulbs fade. Because it is easy about light, use it to carry a planting from a sunny end of the bed into the shadier side.
