Blue Dune Lyme Grass
Elymus arenarius 'Blue Dune'Lyme Blue Dune Grass (Festuca glauca ‘Blue Dune’) is a highly ornamental, compact grass valued for its silvery-blue foliage and tidy, mound-forming habit. Its fine-textured blades create a soft, fountain-like appearance, bringing color, movement, and structure to gardens, borders, rockeries, and container plantings. The cool blue-gray tones provide a striking contrast against greens, golds, and flowering perennials, enhancing visual interest throughout the year. Its low-growing, neat habit makes it suitable for formal garden designs, modern landscapes, and mass plantings that require year-round appeal.
This ornamental grass thrives in full sun and well-drained soil, making it ideal for rock gardens, raised beds, and low-maintenance landscapes. Lyme Blue Dune is drought-tolerant once established and requires minimal care, maintaining its color and compact form with little effort. Occasional trimming of older foliage in late winter or early spring refreshes the plant and encourages healthy growth. Its versatility, hardiness, and vibrant foliage make Lyme Blue Dune an excellent choice for gardeners seeking a striking, reliable accent in a variety of settings.
