PlantFiles: Blue Lyme Grass, Sand Rye Grass
Leymus arenarius 'Glaucus'

For some reason I stuck some of this in my boulevard perennial garden. It is in light shade but is slowly taking over. It roots in really deeply and you cant easily pull it out. It looks OK but really there are much more interesting things to plant. Save this for some special needs area. I'm going to pull out the Round Up.

Extremely invasive in full sun. If you want to cover huge sunny areas in a small amount of time, this is your plant. It will spread in all directions. Lawn grasses still tend to grow in among it easily giving it a messy appearance if not weeded very well when established. Weeding later is a real pain; literally painful due to the sharp leaves.

It is such a pretty hue of blue that we are not ready to give up on it. We will need to try it in shade.

This plant's well-known tendency to invasiveness is easy to control using heavy soil and full shade. The blue foliage remains blue all year when grown in shade. Beautiful upright accent in a shady woodland garden.
