Eastern Bottlebrush Grass (Elymus hystrix) vs. Silky Wild Rye (Elymus villosus)

Updated November 2nd, 2023

These species are sometimes confused, as both are among the earlier Elymus species both to bloom and distribute their seeds, their habitats largely overlap, and both are widely used in ecological restoration projects and occasionally in gardens. They are easy to tell apart by their spikes, and can usually be distinguished by foliage too. E. villosus ranges farther west and slightly farther south, whereas E. hystrix ranges farther north and tolerates more shade and more ground-level competition, but requires more leaf litter in the soil.

Riverbank Wildrye (Elymus riparius) vs. Silky Wild Rye (Elymus villosus)

Updated June 16th, 2023

These two species are visually similar, and can occur together in the same habitat, but they can be easily distinguished by the presence or absence of pubescence as well as differences in their spikes and foliage color. Elymus riparius is more limited to moist, usually riparian habitats, and ranges farther northeast, whereas Elymus villosus can be found in drier habitats as well, and ranges farther west and slightly farther south on the east coast. These species are not known to hybridize.
