Ornamental Grass, Festuca glauca ‘Boulder Blue’

Boulder Blue’ is striking with deep, intense metallic-blue foliage and many more upright flower-stalks that produce lovely wheat-like seed heads on tall, spiky stalks. This is a dwarf blue Fescue that is also considered an evergreen. Regarded by some as the bluest blue fescue, this plant forms compact, cascading mounds of foot-tall, narrow leaves that are attractive in all seasons. Blooms are generally secondary to the foliage, but this cultivar blooms more heavily than most, with spike-lets in summer. This cultivar is long-lived and very hardy. This hybrid is similar to F. ‘Elijah Blue’, but is distinguished by a slightly shorter height, tighter habit, and more upright flower stalks. Grow in groups in a border or rock garden, or as a ground-cover.

General Information +

Botanical: Festuca glauca 'Boulder Blue'

Common: Boulder Blue Fescue

Family: Poaceae

General Characteristics: Foliage is very blue. 'Boulder Blue' is a Uniform Clump Forming Fescue. Drought and heat tolerant. Ornamental Grasses are gaining in popularity all over the U.S. due to their undemanding nature and long lasting, year round beauty. There is nothing that adds such interesting forms, textures and movement to a garden, than with this diverse plant group. They can be planted along banks of ponds, incorporated into perennial gardens, grouped together, utilized as a ground cover along walkways, paths or on steep banks. They aren't fussy about soil requirements, are drought tolerant as well as insect and disease resistant.

Tip: Grows easily in any moderately fertile garden soil. Tolerant of drought, heat, and poor soil. Grow in dry, well-drained soil of poor to moderate fertility in full sun. Divide every 2 to 3 years in early spring. Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. For a neat appearance, remove old foliage before new leaves emerge.

Use: Beds, Borders, Rock Garden and Ground Covers.

Planting/Care Instructions +

Pests or Diseases: Powdery Mildew or Rust.

Planting Instructions: Dig a hole large enough to hold the roots. Fill the hole with water and position the plant so the crown (where the root meets the stem) is just slightly below the soil line. Fill the hole with soil and water again. A slow release fertilizer may be used each spring, though it's not necessary.
