northern mule's ears

Wyethia amplexicaulis is a common herbaceous perennial plant from the northwestern United States called northern wyethia, northern mule ears, or black sunflower. Because of its tendency to grow together in dense colonies and its large, showy flowering heads it is a well known western wildflower that is often photographed. It is disliked by range managers because its leaves are not very palatable to large herbivores including livestock.
