Leymus arenarius 'Glaucus' (Blue Rye) - This is a vigorous deciduous to semi-deciduous psammophilic (sand-loving) species of grass has 18-30-inch-tall upright blue-gray blades and spreads wide by rhizomes. In spring the tight spikes of yellowish green flowers rise a foot or two above the foliage.

Plant in full sun and give average to little water. Good for erosion control and tolerant of beachside conditions. It makes a wide spreading tall ground cover and a good container plant where its invasiveness can be contained. It is very hardy, taking temperatures well below 0 degrees F.

Leymus arenarius is a recently evolved grass that is native to coastal areas in Western Europe up to Northern Europe. It is closely related to Leymus mollis (previously described as Elymus arenarius ssp. mollis) that is native to the northern coastal areas (both Pacific and Atlantic) of North America and it is sometimes sold as Elymus glaucus, which was a previous name for a California native grass now called Leymus glaucus. The name for the genus is an anagram of Elymus, which is derived from the Greek word 'elyo' which means rolled-up or covered in reference to its grain being covered by the flower palea and lemma. Other common names include Blue Lyme Grass, Sand Rye Grass. We have grown this interesting and useful grass since 1987. It similar but stiffer and shorter that the native Rye Grass we grow, Leymus condensatus 'Canyon Prince'
