Summer annual grasses
Texas panicum is a spreading summer annual with relatively wide leaves that may have an erect growth habit, or it may grow close to the ground with tips ascending (decumbent growth habit). Leaf blades range from 3–11 inches in length and may reach a width of 20 mm. Leaves are covered with short, soft hairs on both surfaces. Auricles are absent and the ligule is membranous and fringed with hairs, from 1–1.8 mm long.
Mature Texas panicum.
Collar region: membranous ligule fringed with hairs.
Occurs primarily as a weed of agronomic crops.
Found throughout the southeastern United States but occurs only sporadically in the southern third of Missouri.
Very similar in appearance and growth habit to large crabgrass and broadleaf signalgrass. However, large crabgrass has a tall membranous ligule unlike either of these other species. Broadleaf signalgrass has hairs only along the leaf margins, unlike Texas panicum.
