The leaves of Erica unicolor subsp. georgensis grow in fours around the many branched stems. The leaves are crowded near the tips of the pale yellow to brownish upper stems, dropping off lower down from the old stems, exposing pale grey bark on the woody parts.

The leaves ascend on new growth, later spread. They have short surface hairs. Leaf shape is short, narrow and straight or curving in slightly, tapering to their mucronate tips and the margins rolled under. Leaf colour is pale or yellowish green on new growth, maturing to a darker green (JSTOR; iSpot).
