Blue Oat Grass
Blue oat grass is a graceful, arching ornamental grass with bluish-gray leaves. The thin, spiky leaf blades form a porcupine-like clump. Blue Oat Grass is similar in shape and color to the ornamental blue fescues, except larger.
After flowering at the end of May into June, the tan seedheads are quite attractive throughout the summer, creating an arching fountain form. In the Pikes Peak area, this highly adaptable and decorative grass is a good choice.
