Packera clevelandii is an uncommon species of flowering plant in the aster family known by the common name Cleveland's ragwort. It is endemic to California , where it is known from only two small regions, a section of the North Coast Ranges around Napa County and a part of the Sierra Nevada foothills on the opposite side of the Sacramento Valley. The plant grows in shrubby chaparral on serpentine soils.[1]
It is a perennial herb producing one or more erect stems from a taproot and caudex unit, reaching up to a meter in maximum height. The leaves are thick and fleshy, and have a waxy coating. Their blades are up to 10 centimeters long at the base of the plant, and smaller farther up.
The inflorescence contains several flower heads, each lined with green- or purple-tipped phyllaries (flower bract). The head contains many golden yellow disc florets and 8 to 13 narrow yellow ray florets each under a centimeter long.
