This is an exceedingly variable species with many different varieties. A grayish, woolly, leafy plant with several branched stems ending in short leafless stalks and golden-yellow flower heads. Plants may be erect or sprawling and from 4-18 in. in height. All grow as open, mounds with multiple, spreading branches; white-woolly, lobed leaves; and large (2 in.) yellow, sunflower-like flowers solitary at the ends of stems.
