Sapphire Blue Oat Grass Landscaping Uses

This ornamental oat grass grows into a neat and densely rounded clump of metallic blue foliage. You can use this oat grass variety for just about any spot in your yard. With its mounded form, the oat grass is an excellent composition piece for a garden. The delicate and subtle texture stands out when placed with shrubs and plants that have contrasting textures.

These grasses are excellent selections for mass plantings. If you want a denser planting in your landscape, the Sapphire Blue oat grass needs to be planted 2 feet apart from the center of each clump. With its lush foliage, this ornamental grass even makes a great choice as a loose border around certain parts of your garden.

You should not underestimate the Sapphire Blue’s importance as an accent piece. The fine texture is a great element to add to a perennial or rock garden. With its airy branches, this colorful oat grass gives your space some movement, style, and structure. If you have larger grasses in your landscape, make sure to add this species to those spaces. The Sapphire Blue perfectly combines with the other grasses for a stunning visual impact in your yard.

Sapphire Blue Oat Grass Planting and Care

This ornamental grass is a low-maintenance plant. When it is mature, the Sapphire Blue grows to a width of 24 inches, and it can exceed over 3 feet tall with its flowers. Since the foliage is dense around the ground, it does not need facer plants in front of it. The Sapphire Blue oat grass does grow at a medium rate, and it thrives in USDA zones 4 to 8. Under the right conditions, you can expect this grass to live up to 12 years.

The Sapphire Blue oat grass is a hardy plant, but it should only be grown in areas with full sun. The more sun that you can give this plant, the better results you will have for your yard. The Sapphire Blue oat grass prefers fertile soils, and it loves those alkaline soils. However, it will tolerate those less fertile spots, including clay and sandy soils. In any case, you want to place this oat grass in a well-draining location. Since it can handle environmental salt, the Sapphire Blue is an ideal choice for city landscapes. For the best results, you can cut down this variety in the late winter before the growing season. When spring arrives, you will notice new growth sprouting from the ground.
