Well, though I agree that it looks quite similar (like many grasses), I live on the East coast of Canada. I don't believe they grow here and it's only on the West coast that Leymus Cinereus are found.
We do have a few plants in the genus Elymus, so it could very well be. Information on these plants is scarce, though. I find it amazing how little we know about the flora that surrounds us day to day. Or, perhaps I'm not looking for information in the right place.
Well, the search for Phalaris Arun. Continues!
