Elymus condensatus (syn. Leymus condensatus) is a wild rye grass native to California and northern Mexico. Its common name is giant wildrye. It grows in bunches or clumps, stays green all year, and has a distinctive silver blue foliage. It is drought tolerant, growing in coastal sage scrub, chaparral, southern oak woodland, foothill woodland, and Joshua tree woodlands, rarely in wetlands. It spreads by rhizomes but not rapidly and can be easily contained. It often hybridizes with Leymus triticoides, producing the common hybrid grass Leymus x multiflorus. The cultivar 'Canyon Prince' from the Channel Islands is cultivated as a landscaping grass that is somewhat smaller and more compact than the species.
