Senecio lugens varies greatly in robustness across its range. It is scattered widely in the Rocky Mountain uplift and adjacent regions from northern Wyoming to Alaska; it is disjunct in the Olympic Peninsula, Washington. Superficially similar to S. integerrimus, S. lugens has well-developed, coarse, spreading rootstocks with branching roots; S. integerrimus arises from foreshortened, buttonlike caudices with abundant unbranched, fleshy-fibrous roots.
