P. setaceum is a perennial graminoind of the Poaceeae family that is native to North America. [1]


P. setaceum is found throughout the majority of the continental United States, excepting western states North Dakota, Wyoming, Utah, Nevada, Idaho, Washington, Oregon, and California. It is also found in Ontario, Canada. [1]



Habitats include, sandhills, savannas, and other dry soils. Other varieties can be found in grasslands, pine flatwoods, pince savannas, old fields, and other fields. [4] Specimens have been collected from habitats such as dry sand of grass clearing, wooded ridge with sandy loam, open wet pine flatwoods and mixed hardwood swamps, floodplain forest, shade near lake, coastal hammock, pine flatwoods, fire run in a flatwood, botanical gardens, sandhill, and waste ground. [5]


P. setaceum has been observed flowering in June. [6]

Seed dispersal

This species is thought to be dispersed by gravity. [7] It has been found that gopher tortoises can disperse the seeds of the grass through their scat. The germination success of these partially digested seeds is much lower than those that are not. [8]

Use by animals

P. setaceum provides forage for livestock and deer in Texas. [1]

Birds will eat the seeds.[1]
