Lucerne Blue Eyed Grass

Availability: Out of stock

Stars and Stripes for your garden! Lucerne Blue-Eyed Grass (Sisyrinchium angustifolium 'Lucerne') is a herbaceous perennial that produces lovely blue flowers! This adorable little 'grass' enchants you with Iris-like foliage and petite, yellow-eyed blue blossoms.

The delicate blooms peek out at you amid the foliage from May until June and create a vibrant-green, fast carpet of clump-forming foliage. The centers of each bloom have a bright yellow center and the blooms of this ornamental grass have branched flowering stems.

This variety of the North American native, rambles around Missouri where it naturally occurs in damp open woods, slopes, and along stream banks throughout much of the State. Lucerne are hardy plants for a wide range of growing zones and climates.

Planting and Application:

Plant several in a naturalized area for a splash of color in spring. Creating wonderful groundcover in very little time and filling in between your perennial beds. Plant near where the gutters drain or simply allow it to naturalize meadows and hard to mow hillsides, or in informal garden areas such as cottage and woodland gardens, and native plant areas.

Excellent for edging or the front of mixed borders, or line and define garden beds with upright texture! The star-shaped flowers in bright blue to violet-blue fill in that early summer blooming period with lovely hued color. Wonderful in containers, these provide great upright form and texture fringing the patios, and the sword-like foliage looks lovely planted en masse because they are excellent at stabilizing slopes and stopping erosion.
