Helictotrichon sempervirens (Blue Oat Grass)
The Blue Oat Grass is a striking evergreen variety, its steely blue grey leaves contrast beautifully with many other plants and grasses. In June and July tall, elegant spikes of golden flowers appear, floating and moving in the slightest breeze.
Helictotrichon sempervirens is a wonderfully architectural grass, ideal for bringing height into beds and borders although they are often at their best with space around them, either side of a path right on the edge or in a mediterranean style garden where the form can be appreciated. The steely blue colour contrasts well with many flowers too, especially pinks and they can also look very effective in more contemporary garden designs.
Grow them in any well drained soil, they do well in sun or partial shade.
