Blue Oat Grass, Helictotrichon sempervirens, supplies the landscape with spiky tufts of unmistakable blue ornamental grass. It is non-spreading and will grow 2 - 3' tall and just as wide. Its petite size and vibrant color makes it an excellent little accent plant in rock gardens and small beds. When Blue Oat Grass is planted in mass it makes a specimen species all in itself. Its textural contrast is utilized well among broadleaf shrubs and perennials. This care free plant only needs regular watering the first year and plenty of sun to thrive.
