Actaea podocarpa, the mountain bugbane or mountain black-cohosh, is a species of flowering plant in the Buttercup family. It is native to the Appalachian Mountains, with a single outlying population in northern Illinois. It is found in rich, mesic forests often in boulder-strewn coves. Actaea podocarpa is a large perennial herb. It is one of the later flowering of the eastern Actaea, producing white flowers in summer through fall.
