Lyme grass 'Blue Dune'

Leymus arenarius 'Blue Dune' is admired for its striking steel-blue, broadly upright foliage that provides year-round structure in the garden. During summer, subtle flower spikes emerge above the decorative leaves. This ornamental grass is especially well suited to gravel gardens, coastal-style plantings, and sunny borders. Its bold foliage colour creates a beautiful contrast with flowering perennials and adds a modern touch to the landscape.

Care/Water

Leymus arenarius 'Blue Dune' requires regular watering, especially during the first growing years, to encourage healthy root development. The soil should be well-drained, sandy, and slightly moist, as waterlogging can damage the roots. Water at the base to keep foliage dry and prevent fungal diseases. Consistent moisture promotes strong stems and healthy plant growth.

Maintenance

Regularly remove dead or damaged leaves to improve the plant’s appearance and encourage new shoots. Pruning in late winter or early spring helps renew old stems and maintain vitality. Check the plant regularly for pests and diseases.

Location

This Leymus prefers sunny to partially shaded locations. Well-drained, sandy soil is ideal, as the plant does not tolerate waterlogging. Open sites promote strong stems and a stable plant group.

Tip

Apply mulch around the base in spring to retain moisture and reduce weeds. This supports growth and ensures an attractive, healthy display throughout summer.
