Green foxtail, green bristlegrass
Green foxtail is native to Europe and Asia, but naturalized and widespread in North America now. Eventually this grass was cultivated to become the food crop foxtail millet.

Leaves: Leaf blades are medium dull green, rough but hairless (except sometimes near the edges), and up to 1′ ⨉ ⅞″ (40 ⨉ 2.5 cm).
Flowers: Flowerheads are a green panicle up to 6″ long ⨉ ¼–⅝″ around (15 cm ⨉ 8.5–16 mm), usually erect, sometimes slightly nodding.
Fruits: Spikelets are ~1/16″ (1.8–2.2 mm) long.
Habitats: Margins of woods, upland prairies, streambanks, pond margins, pastures, fields, lawns, cultivated areas, disturbed sites, roadsides, railroads.
