Calocephalus citreus is a perennial herb with upright, slender, light grey, fuzzy, slightly angular stems growing to about 15–60 cm (5.9–23.6 in) high.

The heads are solitary, oblong to globose shaped, about 0.4–2 cm (0.16–0.79 in) long, lemon-coloured in bud, bright yellow in flower. The 8-11 bracts are flat, conduplicate, 1.9–3.4 mm (0.075–0.134 in) long with 2-3 florets per head. Flowering occurs from September to March and the fruit is a cypsela 0.7–0.85 mm (0.028–0.033 in) long, brown, and the upper surface covered in fine, feathery bristles. [2] [3]
