Sisyrinchium 'Lucerne' Description

'Lucerne' blue-eyed grass (Sisyrinchium angustifolium) is a sun loving ground cover with iris-like foliage. Starry blue flowers bloom up to 10 weeks beginning in late spring.

These iris relatives form a fan-like tuft of leaves that stays attractive throughout the year. This clump-forming perennial slowly spreads by creeping rhizomes, making an ideal low maintenance groundcover.  A native alternative to liriope.

It is at home when planted along the edge of a rain garden or stream where it will thrive in a moist setting provided it has sufficient drainage.

Special features: Native, Deer resistant, Easy care, Evergreen, Long blooming, Pest resistant, Rabbit resistant

Spacing: 6"- 12"
Fertilizing: Apply a low dose of high-nitrogen fertilizer in spring.
Winterizing: No special care needed.
Maintenance & pruning: Remove old foliage in spring before new leaves emerge. Most varieties will self-sow; therefore, seed heads should be removed if you don't want it to spread. Divide clumps every 3-5 years in early spring. Easy to propagate by dividing plantlets away from the parent plant. Break off or cut the rhizomes away from the main plant, including the slender foliage of the young plants that form at the base. Plant them as individual specimens for increased spring beauty.
