The succulent, erect, curving leaves of Senecio sarcoides are grown in clusters at branch tips.

They are long and cylindrical tapering to conical tips. The green or blue-grey leaves are longitudinally lined and hairless. Where the waxy bloom sometimes seen on the surface is disturbed, the glaucous leaf colour is changed to a shade of green. The leaf becomes about 6 cm long and 5 mm in diameter (Manning, 2009; Le Roux, et al, 2005; Manning and Goldblatt, 1996; iNaturalist).
