Uses

Cultivated as an ornamental grass, where it is valued for the distinctive appearance of its inflorescence.

There are numerous Elymus (or wild rye) species in North America. Most are native, but the introduced Elymus repens has a wide distribution and is typically considered an invasive species.

Quite a few native species overlap with E. hystrix in range. Some of the more widely-distributed species include E. canadensis, E. submuticus, Elymus trachycaulus, and E. virginicus.

Sometimes occurs together with these grasses in the same habitats; hybridizes with E. virginicus, producing the hybrid E. ×ebingeri.
