How to Grow Blue Fescue


The perennial blue fescue (Festuca ovina var. glauca) grows as a semi-evergreen ornamental mound with waxy blue spears. Height ranges from 6 to 18 inches depending on the variety. From June to July, small green flowers emerge. Seed heads occur following flowering and often sow into the surrounding flower bed. The grass grows well in the United States Department of Agriculture zones 4 to 9. Blue fescue grows well as an edging plant, ornamental grass or a unique ground cover. The grass offers the benefit of an indefinite lifespan and ease of care.

Step 1

Plant blue fescue in full sun or partial shade. Full sunlight produces a more brilliant shade of blue foliage.

Step 2

Choose a site that offers well-draining soil. Blue fescue tolerates a wide range of soils but does not do well in waterlogged locations.

Step 3

Remove flower-heads to maintain the overall mounding appearance of the plant. Cutting flower-heads back will keep the plant from producing seeds that can spread to unwanted locations in the flowerbed.

Step 4

Water blue fescue when the soil dries out. Overly moist conditions will cause the plant to rot.

Step 5

Divide blue fescue every other year. Dig the plant up, divide the outer parts and discard the center. Replant the divisions in new locations.

Step 6

Prune away any brown or damaged grass stalks. Trim the blue fescue if desired to a more compact mound each spring.
