The Boulder Blue Fescue is an outstanding ornamental grass, growing into a dome of fine leaves that radiate out from the crown. The foliage is evergreen in milder climates, and it is a rich, deep, metallic-blue color, much darker and more striking than other varieties of blue fescue. It grows to just under a foot tall and wide, and it is perfect for a foreground accent in a smaller bed, or for edging a larger one. Plant it among rocks and boulders in sunny, dry places ā it will love it, and you will love this great little accent plant. It grows well in planter boxes too.
Full sun and drier soil are best for the Boulder Blue Fescue. It thrives in hot, dry conditions, and it doesnāt like wet soil or high humidity. Plant it in well-drained soil and avoid low-lying areas. Pockets of soil in rock gardens and among boulders are enough, and no fertilizer is needed. This plant is evergreen in warmer zones, where it should be trimmed in spring, before new growth is seen. In colder climates trim in late fall, before the first snowfall. Pests and diseases are normally not an issue, and this plant is deer resistant.
