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'.
