A robust (3–4 m tall!), densely clumped Eurasian grass spreading and beginning to become established, especially along the dry verges of expressways. A vegetative specimen was collected along a roadside in Berrien Co. in 1991 by G. S. Wilhelm & K. Dritz, and a small colony was discovered in 2012, along I-96 in Livingston Co. by A. A. Reznicek & B. S. Walters.
Commonly cultivated for its size and large silky plumes produced very late in the season, it is likely to continue to spread. In addition to the localities mapped, it was also seen along US 127 just north of Lansing, in Clinton Co., but the site was mowed before a specimen could be gathered. Known in older literature as Erianthus ravennae (L.) L. and Saccharum ravennae (L.) P. Beauv.
