Ornamental Grass, Helictotrichon sempervirens ‘Blue Oat’

Blue Oat’ Grass has dramatic powder blue foliage and spiky architecture that are the hallmarks of this plant. The leaves resemble rigid, tapering pieces of steel blue linguine collected in a porcupine-like dome. This grass blooms with delightful, pale blue-green panicle flowers in June to August, turning beige to light brown as the summer wanes. The plant is an evergreen perennial, although with summer drought stress semi-dormancy occurs. It is more long lasting than the blue fescue, making ‘Blue Oat’ Grass is the best choice for accents. The clear blue summer foliage reflects the colors of dwarf blue spruce and blue junipers. For a dramatic effect, try ‘Blue Oat’ Grass with some of the deep maroon leaved canna lilies. Blue oat grass is such a striking sight that is has the ability to stop one dead in their tracks. Divide evergreen or neutral grasses and grass-like plants in spring only.

General Information +

Botanical: Helictotrichon sempervirens 'Blue Oat' Grass

Common: Ornamental Grass

Family: Poaceae

General Characteristics: Combines well with purple- or silver-leaved plants. Deer resistant! 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: Helictotrichon is a neutral grass. Evergreen or neutral grasses are usually plants that look like grasses but aren't actually classified as grasses, they are generally called grass-like plants. Evergreen grasses don't ever go dormant. Dividing plants wounds them to some degree. For evergreen grasses this wounding will really affect their ability to live through the winter. Grow in well-drained, poor to moderately fertile, alkaline soil. Tolerates gravelly, infertile soils. Remove dead leaves and old flowers in spring. Tolerates drought once established. Propagation - Sow seed in spring, or divide clumps in spring.

Use: Blue Oat' grass is great in planters. It is a Bunchgrass often used as an ornamental grass. It is a wonderful addition in most any garden design or landscape.

Planting/Care Instructions +

Pests or Diseases: 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.
