Description

Blue Oat Grass is a stunning perennial that delivers a refreshing splash of blue-green foliage to any landscape. In Michigan’s cooler climate, its compact, clump-forming habit creates a neat, polished accent perfect for borders or container plantings. Throughout the summer, its airy flower panicles add a satisfying textural interest and a touch of elegance. This versatile grass thrives in full sun and well-drained soil, making it an inspiring and low-maintenance choice to elevate your outdoor space with its bold, modern beauty.

General Care

• Sunlight: Requires full sun—at least 6 hours of direct light daily—for optimum growth and vibrant color.
• Soil: Prefers well-drained soil enriched with organic matter to support steady moisture and healthy development.
• Watering: Provide consistent moisture during the growing season to maintain its refreshing, compact form in Michigan’s cooler conditions.
• Mulching: A 2–3 inch layer of mulch around the base helps conserve soil moisture and regulate temperature; keep mulch slightly away from the clump to ensure proper airflow.
• Pruning: Remove any dead or browning foliage to keep the clump tidy and to encourage vigorous new growth.

Blue Oat Grass adds a gorgeous, uplifting accent to Michigan landscapes, offering a refined and inspiring display of blue-green beauty that stands out year-round.
