More Information

White Rattlesnake-root is one of the few flowering plants seen in the woods towards the end of summer. It can also be found in smaller forms, typically with smaller, less variable leaves, in rock outcrops and on the rocky shore of Lake Superior. The flower shape is similar to other Prenanthes species, but P. alba is distinguished by its branching clusters of dangling white to pinkish flowers with hairless, purplish bracts, smooth stem and (typically) variable leaf shapes. In some references, P. alba is known by synonym Nabalus albus.
