Mount Patterson Senecio
Senecio pattersonensis
About Mount Patterson Senecio (Senecio pattersonensis) 0 Nurseries Carry This Plant Senecio pattersonensis is an uncommon species of flowering plant in the aster family known by the common names Mono ragwort and Mount Patterson senecio. It is known only from a small stretch of mountain peaks straddling the border between Mono County, California, and Mineral County, Nevada, in the western United States. It grows in rocky high mountain habitat in an alpine climate, such as talus and fellfields. It is named for Mount Patterson, the highest peak in the rugged Sweetwater Mountains of Mono County. This is a small perennial herb producing one to three stems from a rhizome, the plant generally not exceeding ten centimeters in height. The herbage is hairless and green to red in color. The leaves are thick and often fleshy, measuring 2 to 4 centimeters long. They are narrow and linear or lance-shaped, sometimes with wavy edges or divisions into lobes. The inflorescence bears one to four flower heads containing yellow disc florets and usually 8 ray florets measuring one half to one centimeter in length.
