This showy perennial of the lily family makes compact, many-stemmed clumps. Each shoot consists of a spray of folded grassy leaves, up to 12 inches long, and one or more taller, well branched flower stems, appearing in early summer. For several weeks these carry a succession of starry one inch flowers, bright true-blue in color. Then the plants disappear until fall rains begin. Sun, well drained soil, little or no summer irrigation (making it an ideal subject for naturalistic meadows and banks). Hardy to 15 degrees F. or less.
