Leymus arenarius, Blue Dune - Prairie

Leymus arenarius 'Blue Dune' is the electric-blue rebel of ornamental grasses—the European dune dweller that brings coastal cool to Indiana landscapes with its intensely metallic steel-blue foliage that practically glows like alien metal in the sunlight. Wide, flat blades arch gracefully from the clump, holding that stunning powdery blue-gray hue through the seasons, with subtle wheat-colored flower spikes rising discreetly in midsummer like polite barley whispers, turning beige for fall and winter texture.

Homeowners love its bold versatility: plant it for erosion control on slopes (it stabilizes like a champ), create a fast-filling groundcover in tough dry spots, use as a dramatic accent in xeriscapes or rock gardens, line seaside-inspired borders, or contain it in large pots for patio punch—though fair warning, this vigorous rhizome-spreader can turn into a garden conqueror if given free rein, so choose open areas wisely or barrier it like a mischievous puppy.

Thriving in full sun (partial shade tolerated but dulls the blue intensity), it reaches 2-3 feet tall and spreads 2-4 feet or more—perfect for big-impact statements. Extremely drought-tolerant once established (ideal for forgetful waterers), salt- and heat-resistant, deer-proof, and low-maintenance in poor, dry soils. Minimal pollinator appeal from the subtle blooms. In zone 6a Indiana, this hardy perennial (zones 4-9) delivers effortless, four-season seaside swagger.
