Leymus condensates (Wild Rye) - This medium-sized powdery gray-blue rhizomatous evergreen grass (new foliage emerges green) grows 2-3 ft. tall in a drier location and up to 5 ft. tall when given regular water. The erect flower stalks rise 1-2 ft. above the foliage in late summer and are topped with wheat-colored flowers. Plant in full sun to light shade, but color is best in the sun. It is drought resistant but looks best with occasional irrigation along the coast and needs it in inland and desert gardens. This grass has proven hardy to below 10 degrees F. It spreads by short rhizomes and with time can colonize large areas, if so desired and not contained, but its growth can be restricted by selective removal of rhizomes along the edge of the planting or by using a physical barrier (paving or plastic root barrier). Avoid over irrigating as it can lose its typically upright form and lie flat as though sat on. We like to cut this plant back once a year in late spring to late summer to freshen it up but don't be surprised that the newly emerging shoots are bright green; they will rapidly turn blue-gray again as they mature.
