Blue Dune Lyme Grass
Blue Dune Lyme Grass (Leymus arenarius’ Blue Dune’) is a striking ornamental grass known for its silvery-blue foliage and robust growth. Perfect for adding texture and color to coastal and dry landscapes, this grass thrives in full sun and well-drained soils, making it an excellent choice for erosion control on sandy or rocky slopes. The bold blue-gray blades create a stunning contrast in the garden, and the grass produces wheat-like flower spikes in mid-summer, adding vertical interest. Blue Dune Lyme Grass is also highly salt-tolerant, making it ideal for seaside gardens or areas exposed to road salt.
This hardy grass grows well in USDA Hardiness Zones 4-9, withstanding a wide range of temperatures and weather conditions. Blue Dune Lyme Grass reaches a mature height of 24-36 inches and spreads up to 36 inches wide, making it an excellent option for mass plantings, borders, or as a ground cover in challenging environments. Its vigorous spreading habit allows it to establish quickly, filling in gaps and creating a dynamic, low-maintenance landscape. While it’s known for its aggressive spread in some areas, it can be easily controlled with regular pruning or by planting in containers.
In addition to its eye-catching beauty, Blue Dune Lyme Grass is highly drought-tolerant once established, requiring little to no supplemental watering. This makes it a popular choice for xeriscaping and sustainable landscapes. Whether you’re looking to stabilize sandy soil, create a low-water garden, or add striking color to your landscape, Blue Dune Lyme Grass is a versatile and resilient option that delivers year-round interest with minimal care.
