orchard grass, Dactylis glomeratus

Orchard grass is one of the most common causes of hayfever.  Too bad it's so useful.  Orchard grass has the highest sugar content of any northern species.  It's commonly planted for fodder.  The alternative name catgrass is because cats and dogs prefer it when they feel the need to graze.  Thanks to agriculture, this annoying pollen is now available pretty much anywhere.  With us it occurs in every state and province except LB, NT, NU, and YT, and on GL and SPM.  And yes, I know LB isn't a separate province, but it is often mentioned separately when the ranges of Canadian plants are shown.  Lenawee Co MI, 6/7/12.  Grass family, Poaceae.
