Senecio actinella is an herb that can form large mats in clearings in Ponderosa Pine forest. The mat is formed by the older glabrous and shallowly dentate basal leaves. The newer leaves are more ascending, entire and tomentose. The scape is nearly leafless except for perhaps one or two bract-like leaves. The inflorescence is solitary, which easily differentiates it from the Senecio wootonii with which it is commonly found.
