Blue Wildrye (Elymus glaucus)
A native, perennial bunchgrass from western North America with blue-green foliage that provides erosion control, habitat, and food for wildlife. It is a cool-season grass that tolerates drought, a variety of soils, and both full sun and partial shade. Blue wild rye has tall stems and flower spikes that mature from green to tan, and the foliage and dried flowers persist through winter.
Sun: Full sun to partial shade.
Soil: It is adaptable but performs best in average to dry, well-drained soils and does not need rich soil. It tolerates a variety of conditions.
Height: typically grows between 30 to 180 cm (1 to 6 feet) tall, with the height varying depending on the specific subspecies and growing conditions.
Spread: about 12 inches (30 cm) in width
Garden Design:
Plant in sunny or partially shady areas with average, well-drained soil. It is well-suited for dry slopes, xeriscaping, and matrix meadows, and can also be a striking 'thriller' centrepiece plant in containers. To maintain Blue Wild Rye, prune it back in late winter to early spring and manage its size with selective pruning if needed.
