Blue oat grass is a striking evergreen perennial grass with distinctive blue-gray foliage and a clumping habit that can reach 24-30 in. high. Tall wheat colored inflorescences develop in early summer and grow 6-12 in. above foliage.

Blue oat grass is well suited as a contrasting element in mixed perennial plantings, rock gardens and containers. Native to the western Mediterranean region, it is a cool season grass that grows best with good drainage and regular moisture throughout the year; avoid planting in garden spaces with hot afternoon sun. It grows well in containers, along dry stream beds and among flowering perennials on banks and in parkways.
