The tuft of Senecio spiraeifolius leaves emerges at ground-level around the erect flower stem, spreading like a rosette.
Pale green to blue-green, the leaves are long and narrow, their many short, broad lobes twisting and bulging in a complex but regularly repeated pattern from base to tip. The midrib is sunken on the upper surface and sometimes whitish, the incisions between the lobes not quite deep enough to reach it. The leaves in picture have thick, purplish petioles below the lowest blade lobes.
Many more leaves than in the photo may make up a strong plant’s endowment, the leaves sometimes angled up rather than curving down (Manning and Goldblatt, 1997; iNaturalist).
