Question
Good evening. the inflorescence of this grass looks like some of the barleys or foxtails, But i could seem to find a good match in the guide. Can you zero me in? It's on the upper bank of the salt marsh, Joppa Flats Ed Center. Thanks.
Answer
Dear chafeemonell, the grass in the picture is likely Setaria pumila (yellow foxtail), a species that has been called Setaria glauca in older literature. It is a fairly common, non-native grass that grows in open, disturbed areas. There is a native species in this genus (Setaria parviflora) that grows at the edges of tidal marshes, it is a perennial with knotty rhizomes. However, The Joppa Flats Education Center is likely just out of range of this species, but you might check to see if you have a new county record.
