General description

There are several selections of Blue Fescue, all of them valued for their clumping habit, and display of colourful, grassy foliage. This is considered to be one of the best blue selections, retaining its colour all season. Tan spikes appear in early summer. Excellent for mass planting, edging, or in the rock garden. Clumps are easily divided in early spring, and this should be done every 2 to 3 years. Evergreen in mild areas, in colder winter regions the leaves should be trimmed back in late winter right to the base. Flower spikes may also be removed in summer, if desired.

Plant requirements

Plant Elijah Blue in full sun and in a well-drained soil. The more sun this ornamental grass receives, the more likely it is to achieve its signature blue-gray color.

  • Sun Exposure - Full Sun or Partial Shade
  • Soil Type - Normal, Sandy or Clay
  • Soil pH - Neutral, Alkaline or Acid
  • Soil Moisture - Average or Dry
  • Care Level - Easy 


  • Plant Elijah Blue fescue in a sunny spot, in soil that has been prepared ahead of time.
  • To prepare for planting dig or cultivate the soil to a depth of 10 to 12 inches. Dig a hole large enough to accommodate the roots, then place the divided plant in the hole.
  • Adjust the depth of the hole if necessary, as the fescue should be planted at the same soil depth at which it was previously planted.
  • Pat the soil around the roots to eliminate air bubbles, then water thoroughly.


  • Keep the soil moist until new growth appears, then provide Elijah Blue fescue with about an inch of water every week during warm weather.
  • Water slowly at the base of the plant and don't spray the foliage.
  • Cut back Elijah Blue fescue with hedge shears, a weed trimmer or pruners every year in late winter or early spring. Cutting back yearly will remove old growth, keeping the grass vigorous and attractive.

Practical use

Because it is a relatively short ornamental grass, Elijah Blue can be used in the front rows of flower beds, without risk of obscuring views and/or shading. Its fine plant texture provides a nice contrast to plants with coarse textures.

Use it as a ground cover en masse and/or in conjunction with mulch. The drought tolerance of this ornamental grass makes it a popular plant for rock gardening.
