Mounds of tough leathery grass-like leaves. Spike like purple flowers stalks. Creamy yellow leaf borders. High light improves color. Full sun to full shade. Average to rich well drained soil. Almost as tough as its green counterpart. Excellent for edging or in the front of a perennial border. A superb groundcover. Combine with columbines, lupines, ligularia, yucca, or any colorful blooming annual or perennial.
