Senecio integerrimus is a species of flowering plant in the aster family known by the common names lambstongue ragwort^[1] and tall western groundsel. It is native to western and central North America, where it grows in grassland, forest, and other habitat. It is a biennial or perennial herb producing a single erect stem 20 to 70 centimeters tall from a caudex with a fleshy root. The linear to lance-shaped or triangular leaves have blades up to 25 centimeters long. The herbage is slightly hairy to woolly or cobwebby. The inflorescence bears several flower heads in a cluster, the middle, terminal head often largest and held on a shorter peduncle, making the cluster look flat. The heads contain many disc florets and usually 8 or 13 ray florets which may be yellow to cream to white in color. Some heads lack ray florets.
