Triosteum perfoliatum
Also called Common Horse Gentian, Late Horse Gentian, Perfoliate Horse Gentian, Perfoliate Tinker's Weed, Common Horsegentian
Triosteum perfoliatum, commonly known as perfoliate tinker's-weed, late horse gentian, common horse gentian, perfoliate-leaved horse-gentian, feverwort, and wild coffee, is a species of flowering plant belonging to the family Caprifoliaceae (honeysuckle). It is found in eastern and central North America. The yellow-orange berries can be dried, roasted, ground, and used as a coffee substitute.
T. perfoliatum is native in the United States from Nebraska to the west, Louisiana to the south, Massachusetts to the east, and the Canadian border to the north. In Canada, it is native in Ontario, where it is an endangered species. In Louisiana, it is possibly extirpated. It is extremely rare in both Massachusetts, where it is endangered, and Rhode Island, where it is a species of concern. It can be found in open woods on hillsides or valleys in dry areas.
