Taxonomic Notes

Synonym: T. intermedia (Nash)

Variety: none


T. purpurea is an annual graminoid of the Poaceae family that is native to North America. [1]


T. purpurea is found throughout the continental U.S. except Washington, California, Nevada, Arizona, Utah, Idaho, Wyoming, Montana, and Minnesota. It is also found in Ontario. [1]



Common habitats for T. purpurea include Dunes, maritime dry grasslands, and open sandy areas. [2] It is considered a weedy species that can develop in disturbed areas such as old fields that have not been without agricultural use for long. [3]

Some samples have been taken from dry loamy sand in longleaf pine woods, roadsides, flatwoods, sand dunes, hammock clearing, slash pine woodlands, guld coastal plain, oak sand ridge, and other moderately disturbed sites. [4]
