Lyme Grass, Wild Rye
Ornamental grasses and grasslike plants
These wild ryes or lyme grasses were formerly assigned to Elymus but are now known as Leymus (simply an anagram of the former generic name). They are grown principally for their blue-gray or silvery blue foliage. Very drought-tolerant; will remain evergreen with some summer water.
From coastal northern and western Europe. A low, vigorous clump of gray-blue leaves is topped by clusters of inconspicuous flowers. Grows to 3–4 ft. tall in bloom, spreading widely by thick rhizomes. Good soil binder; may need curbing. Flowers are not especially attractive, and the plant looks best when cut back after bloom to stimulate fresh foliage. Does best in cool weather but withstands considerable heat. Grows in sandy soils in the wild; tolerates clay soils.Leymus condensatus
Native to coastal Southern California and the Channel Islands. The species is usually green leafed, reaching 9 ft. tall and 6 ft. wide in bloom. More commonly grown is ‘Canyon Prince’, to 4 ft. tall and 3 ft. wide; foliage is green when new, maturing to brilliant silvery blue. Spreads slowly by rhizomes.
