More intense pastel blue blades are coveted for landscapes. Slender beige flower spikes rise a foot above foliage in late summer. Spreads vigorously by rhizome, filling in large areas quickly, may require containment. Tolerant of seasonal clean up by mowing at winter's end. Important problem solver for wind, salt air and sandy soils along the immediate coast. Although drought resistant, adequate watering ensures best foliage quality. Herbaceous. Full sun or light shade. Very fast growth to 2 feet tall and spreading indefinitely.
