Houghton's goldenrod

This showy, shoreline goldenrod grows nowhere else in the world but along the Great Lakes shoreline. It grows primarily along the northern shores of Lakes Michigan and Huron. Most populations of Houghton's Goldenrod occur in Chippewa, western Mackinac, northern Emmet, Cheboygan, and northern Presque Isle Counties. Outside of Michigan it extends to the Bruce Peninsula in Ontario, Canada.
