Green foxtail seedhead. |

Life cycle: Erect summer annual.
Stems: Erect, mostly 3-foot-tall stems are branched and clump-forming at the base. Stems are usually round but are occasionally flattened in cross-section.
Reproduction: Seeds.
Ligule: Hairy.
Flowers and fruit: The seedhead is a dense, cylinder-shaped, foxtail-like panicle with green to purple bristles. Usually erect to slightly nodding seedheads are capable of producing prolific amounts of oval to egg-shaped, yellowish brown seeds.
Leaves: Leaves are hairless, rough, rolled in the bud and up to 12 inches long. Leaf sheaths are hairless except for short hairs along the margin. |

Giant foxtail (S. faberi Herrm.) Differs by having a larger, up to 7-foot-tall stature, leaves with numerous short hairs on the upper surface, and longer, highly nodding panicles.
Yellow foxtail [S. glauca (L.) Beauv.] Differs by having long, wispy hairs on the upper leaf surface near the stem, a panicle with yellowish brown bristles, and a yellow to light brown seedhead at maturity. |
