The scale-like, knob-like or granular leaves of Phaenocoma prolifera are closely spaced and tightly pressed to the stems. They grow overlapping on short side-shoots. The leaves are only about 2 mm long.
The leafy side-branchlets grow at right angles from the stiff, woody stems that become white and woolly. Each branchlet is subtended by a brown bract (Vlok and Schutte-Vlok, 2015; Manning, 2007; Bean and Johns, 2005; iNaturalist).
