Vernonia fasciculata Michx.

Coefficient of Conservatism: *
Coefficient of Wetness: -3
Wetness Index: FACW
Physiognomy: Ad P-Forb

Roadsides and fields, mostly spreading from plantings; introduced from west and south of Michigan.

Though the native range of this species reaches central Wisconsin and northern Indiana, all our records are plants spreading from restorations or mitigation sites, where clearly originally planted, or along roadsides. First collected by T. L. Walters in 2004 as “occasional” in the upland portion of a wetland mitigation site in Wayne Co. Also well established and apparently self-sowing at a prairie restoration in Oakland Co. More recently collected along a roadside in the western Upper Peninsula in 2019 by A. Graeff, but with weedy associates, not in the context of a remnant prairie.
