Chasmanthium latifolium, known as woodoats, inland sea oats, northern sea oats, and river oats is a grass native to the central and eastern United States, Manitoba, and northeastern Mexico; it grows as far north as Pennsylvania and Michigan,[1] where it is a threatened species.[2] The species was previously classified as Uniola latifolia (André Michaux).


Chasmanthium latifolium is a cool-season, rhizomatous perennial grass with stems about 1 m [3 feet] tall.[3] The plant typically grows in wooded areas and riparian zones.[4]

It is used in landscaping in North America, where it is noted as a relatively rare native grass that thrives in partial shade; the plant is recommended for USDA hardiness zones 3-9 in acidic sands, loams, and clays.[5][6]
