Festuca glauca Boulder Blue

Festuca glauca ‘Boulder Blue’ is a compact, evergreen ornamental grass prized for its intensely bright, silvery-blue foliage and refined, mounded habit. Forming dense, tidy clumps, this selection stands out for its vivid coloration, which holds well through the growing season and provides striking contrast against green or warm-toned plantings.

In early summer, slender stems rise just above the foliage, carrying soft, buff-colored flower spikes that add a delicate, airy texture. As they mature, the blooms fade to a light tan, extending visual interest without overwhelming the plant’s clean form.

Highly adaptable and low maintenance, ‘Boulder Blue’ thrives in full sun and well-drained soils, showing excellent drought tolerance once established. Its compact size makes it ideal for edging, rock gardens, mass plantings, and container use, where its bold color can be appreciated up close.

With its vibrant hue, neat structure, and dependable performance, Festuca glauca ‘Boulder Blue’ is a versatile accent that brings year-round texture and cool-toned brilliance to the landscape.
