Eriophyllum lanatum
The common woolly sunflower (Eriophyllum lanatum), also known as Oregon sunshine, is a common, widespread, North American plant in the sunflower family.
Lewis and Clark saw Eriophyllums growing above their camp on the Clearwater near present day Kamiah, Idaho. They gathered two specimens (the plant was then unknown to science) on June 6, 1806.
