Blue fescue (Festuca glauca) is a low-growing ornamental grass prized for its attractive blue-gray foliage and compact growth habit. Here's some information about it:

1. Description: Blue fescue forms dense clumps of narrow, fine-textured foliage. The leaves are typically blue-gray to silver-blue in color and have a tufted or fountain-like appearance. In early summer, it may produce inconspicuous flower spikes that rise above the foliage. However, the primary appeal of blue fescue is its attractive foliage rather than its flowers.

2. Growing Conditions: Blue fescue thrives in full sun and well-drained soil. It is drought-tolerant once established and prefers lean, sandy or rocky soil. Blue fescue is relatively low-maintenance and does not require fertilization. It is tolerant of salt spray and is often used in coastal landscapes.

3. Landscaping Uses: Blue fescue is versatile and can be used in a variety of landscaping applications. It is commonly used as a ground cover, edging plant, or accent plant in rock gardens, borders, and container plantings. Its compact growth habit and striking foliage make it a popular choice for adding texture and color to mixed perennial beds and landscapes.

4. Maintenance: Blue fescue is low-maintenance and generally requires little care once established. It may benefit from occasional watering during prolonged dry periods, especially in hot climates. Dead or damaged foliage can be trimmed back in early spring to promote new growth and maintain the plant's appearance.

5. Propagation: Blue fescue can be propagated by division in early spring or fall. Simply dig up the clump and divide it into smaller sections, ensuring each division has some roots attached. Replant the divisions at the same depth as the parent plant and water thoroughly.

Overall, blue fescue is a beautiful and versatile ornamental grass that adds color and texture to the landscape with its striking blue-gray foliage. With its easy-care nature and adaptability to various growing conditions, it's a popular choice for gardeners looking to enhance their outdoor spaces.
