Needle-and-thread Grass is a common grass of the Great Plains and reaches the eastern edge of its native range in Minnesota; it's considered introduced farther east.

Needle and thread generally requires at least 10 inches (254 mm) of annual precipitation [44] but grows in areas with less [130]. Silty clay subsoils layers were calcareous at about 15 inches (38 cm). comata:

Florets are surrounded by a pair of bracts (lemma and palea), the lemma thicker than the glumes, 5-veined, 7 to 13 mm long, hairy, narrowly lance-linear with a stiff awn 4 to 8 inches long covered in short, stiff hairs; the palea is about as long as the lemma and similarly hairy.

In 1976, the year of the fire, needle and thread yield was significantly (p<0.10) higher in the burn than in the unburned control. 607   Wheatgrass-needlegrass Structure and ecology of coniferous forests of the northern Rocky Mountains [43]

The aspect on which needle and thread appears most frequently varies by geographic location. It has a wide distribution spanning from northern Canada to Mexico.[1]. In southwestern Saskatchewan, needle and thread often dominates on loam soils but is usually absent from heavy clays [83]. 611   Blue grama-buffalograss

In 1997, 6 plants that were absent (and presumed killed) in 1996 resprouted and produced seed, and 5 plants present in 1996 were not found in 1997. This was a ponderosa pine (Pinus ponderosa) and mixed-grass prairie site, featuring a western wheatgrass (Pascopyrum smithii)-needle and thread plant community.
