Common name: Blue-Eyed Grass, formerly bermudianum.
Zone 5 to 8, maybe 4 to 9.
Full sun to part shade.
Plants reach 10 inches tall and 15 inches wide, clump-forming perennial.
Growth rate: Moderate, semi-evergreen.
Spiky, dark green, fan-like clumps of narrow, stiff grass-like foliage gives way to bright purplish-blue flowers with six pointed tepals and gold centers. One inch blooms appear the heaviest in late spring and early summer. Plants may continue to bloom sporadically all summer long.
This plant is very low-maintenance. It will grow in full sun or partial shade and prefers average to rich, well-drained soil. Prefers consistently moist soils that do not dry out, but drainage must be good. Plants spread slowly to form thick clumps. Plantings may be sheared back after bloom to tidy foliage for remaining part of the growing season. Divide after flowering if desired. 'Lucerne' does not vigorously self-seed as often as species plants.
This is a great little plant for accents along walkways or in rockeries. It has a very unique look. Though it looks like it belongs to the family of plants, it is actually a relative of the Iris family.
