BOULDER BLUE FESCUE GRASS

Festuca ovina var. glauca 'Boulder Blue' is an exceptionally hardy and compact ornamental grass, often favored for its deep, intense metallic blue coloration. This cool-season fescue forms a dense, stiffly upright mound of needle-like foliage that typically reaches about 6 to 9 inches in height and 6 to 12 inches in width. While many blue fescues can appear slightly "washed out" in the peak of summer, 'Boulder Blue' is known for its ability to retain its vivid, steely hue even through periods of high heat and humidity. In late spring to early summer, it produces slender, wheat-like flower spikes that rise above the blue tufts, maturing into a soft, golden-tan seed head.

Caring for 'Boulder Blue' is remarkably simple, as it thrives on neglect and requires "lean" conditions to look its best. It performs most vibrantly in full sun, which is essential for maintaining its signature blue wax coating; in too much shade, the plant will turn a duller green and lose its tight, mounded shape. This grass must have sharply drained soil and is highly drought-tolerant once established, making it a perfect candidate for rock gardens, sandy slopes, or as a modern architectural edging.

Planting Tips ⓘ

To help Festuca settle in and thrive, we recommend these standard planting practices: Plant in full sun in lean, sharply well-draining soil. Festuca varieties are cool-season, clumping grasses that are highly sensitive to soil moisture; avoid heavy, wet, or overly rich garden soils, as these will cause the crown to rot. Excellent drainage is essential to maintaining their signature blue foliage color. In early spring, use a hand rake to gently 'comb' out dead foliage from the clumps. Avoid cutting them to the ground like larger grasses, as they do not regenerate well from hard pruning.
