The erect, opposite leaf pairs of Lampranthus sociorum are thickly succulent, more three-angled than cylindrical from the keels present. The leaves are slightly incurved to straight with pointed tips turning in, sometimes red. The smooth leaf surfaces are pale blue green, sometimes blue grey, while old leaves turn pale and become orange.
The buds among the leaves have pedicels still elongating. They are paler than the leaves, preparing to open soon. At this stage the buds are much about erect sepal lobes, not quite making it masquerading as leaves. There are five of them to a bud, the two at the ends of the not quite round bud are slightly bigger (Smith, et al, 1998; Bond and Goldblatt, 1984; iNaturalist).
