This native tall grass prairie-grass once covered hundreds of square miles of the Missouri River bottomlands. It is also found on sand dunes in the Great Lakes. It has always been rare in the Windsor/Essex County, Ontario region but occurred pre 1900 locally on open sand at Point Pelee as well as across Lake Erie on the Ohio shore. While a widespread native in Maine, it is now endangered and highly localized on a few shorelines and riverbanks within the state.

The showy golden plumes, up to 7 rarely 12 feet, borne late summer. The individual plumes are up to 12 inches in length.
The seed heads are attractive during fall and winter.
Hardy zones 3 to 8 ( possibly 2 for northern North Dakota seed source ) in full sun on just about any fertile, well drained soil. Tolerant of drought and heavy clay soil. Cut back hard during late winter. Propagation is from division done during early spring or seed being sown at 0.25 inches deep. Deer resistant and not prone to pests or disease.
