• Sisyrinchium angustifolium - Narrow-leaf Blue-eyed-grass


    "Sisyrinchium campestre is noted for its pale blue to white flowers and unbranched flowering stems. It occurs in open woods, glades, prairies and grassy areas.... It is a clump-forming perennial that features a tuft of narrow grass-like leaves (to 3/16" wide) typically growing to 6" (less frequently to 10") tall. Clusters of pale blue to white flowers (to 1/2" across), each with 6 pointed tepals and a yellow eye, appear in spring on stalks growing from leaf-like bract atop unbranched flowering stems which are distinctively flattened. Sisyrinchium angustifolium, also a Missouri native, features violet-blue flowers atop branched flowering stems.

    "Specific epithet means of the fields.

    "Though their foliage is grass-like, the blue-eyed grasses belong to the iris family not the grass family."  (Missouri Botanical Garden)


    "Best grown in medium moisture, well-drained soil in full sun. Tolerates light shade. Prefers consistently moist soils that do not dry out, but drainage must be good. Will freely self-seed in optimum growing conditions. Plantings may be sheared back after bloom to avoid any unwanted self-seeding and/or to tidy foliage for remaining part of the growing season. Plants may need to be divided every 2-3 years to keep plantings vigorous."  (Missouri Botanical Garden)
