Sisyrinchium angustifolium, commonly called blue-eyed grass, is noted for its violet-blue flowers and branched flowering stems. It is a clump-forming perennial that features a tuft of narrow grass-like leaves (to 3/16" wide) typically growing to 12" (less frequently to 20") tall. ‘Lucerne’ was discovered growing in a nursery near Lucerne, Switzerland. It is noted for its profuse bloom of large, one inch diameter, star-like, intense blue flowers with yellow centers over a long May-June bloom period.
