Extremely popular in the southern U.S. as groundcover plants, these are now becoming known elsewhere, and valued for their versatility. Plants form a clump of grass-like foliage, bearing spikes of tiny lily flowers in summer. This selection has light-green leaves striped with yellow to cream, and deep-blue flower spikes. If plants look shabby in spring, trim the leaf tips with sharp scissors, or just mow back hard. Easily divided in spring. Where hardy, this is an excellent choice for edging, in rock gardens, or in mixed containers. Tolerates summer heat and humidity. Evergreen.
