Blue Fescue Ornamental Grass Seeds | Festuca glauca | Drought Tolerant Perennial

Blue Fescue Ornamental Grass Seeds – Festuca glauca

Blue Fescue (Festuca glauca) is a low-growing, evergreen to semi-evergreen perennial ornamental grass prized for its striking silvery blue-grey foliage, compact clumping habit, and exceptional drought tolerance. One of the shortest ornamental grasses available — topping out at just 10 inches — it’s a versatile, low-maintenance choice that earns its place in borders, rock gardens, mass plantings, wildflower mixes, and ground cover designs.

A waxy leaf coating reduces water loss, allowing Blue Fescue to thrive through extended dry spells — and drought stress actually deepens the intensity of its blue color. This is a grass that rewards a little neglect with outstanding beauty.

Plant Details

• Species: Festuca glauca (syn. Festuca cinerea)

Germination Instructions

• Soil Temperature: 68°F
• Germination Time: 2–3 weeks
• Sowing Depth: Do not cover seeds — press firmly onto the soil surface; light aids germination
• Sowing Rate: 3 seeds per plant
• Spacing: 12 inches apart
• Moisture: Keep consistently moist until germination

Starting Indoors vs. Direct Sowing

• Indoors: Start in late winter in small peat pots or containers filled with seed-starting mix. Press 3 seeds per pot onto the surface; lightly cover and keep moist.
• Outdoors: Direct sow after all frost danger has passed. Loosen and weed soil, amend with seed-starting mix, and space seeds 12 inches apart.
• Once seedlings reach 4 inches, bundle leaves and trim ½ inch — this encourages stronger root development and a tidier, uniform habit.
• Note: Seedlings emerge green; the characteristic blue color develops as the plant matures.

Ongoing Care

• Cut plants back to 2 inches in early spring to refresh growth.
• Trim flower heads after bloom to prevent unwanted self-sowing.
• Very shade tolerant — thrives in dry shade beneath trees where little else grows.
• Mixes beautifully with wildflowers without crowding or competing.
• Excellent low-maintenance ground cover when planted in mass.
