Blue Eyed Grass 'Moody Blues'

Blue-eyed grass, commonly known as Sisyrinchium angustifolium, has violet-blue flowers and branched flowering stems. Blue-eyed grasses belong to the iris family, not the grass family, despite their grass-like foliage. 

This perennial forms clumps and typically grows to 12" tall with its narrow grass-like leaves. The violet-blue flowers, which have six pointed tepals and yellow eyes, appear in spring on stalks growing from leaf-like bracts atop usually branched flowering stems that are characteristically flattened. Plants formerly classified as S. bermudianum are included in Sisyrinchium campestre, which has pale blue to white flowers atop unbranched flowering stems.

It grows best in medium moisture, well-drained soil in full sun to part shade. The soil must be consistently moist and not dry out, and the drainage must be adequate. Optimal growing conditions will allow it to self-seed freely. Shear back plantings after bloom to prevent unwanted self-seeding and keep foliage tidy for the remainder of the growing season. Plants must be divided every 2-3 years vigorous.
