Chasmanthium latifolium, known as Woodoats, Inland sea oats, Northern sea oats, and River oats is a grass native to the southeastern United States and northeastern Mexico; it grows as far north as Pennsylvania and Michigan, where it is a threatened species. The species was previously classified as Uniola latifolia (André Michaux).
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.
