Description
Cassinia nivalis is an erect shrub that typically grows to a height of 1–2 m (3 ft 3 in – 6 ft 7 in), its branches deep reddish-purple and hairy. The leaves are needle-shaped, 15–25 mm (0.59–0.98 in) long and 0.5–0.7 mm (0.020–0.028 in) wide, the upper surface of the leaves glossy green, the edges rolled under and the lower surface densely covered with white, cottony hairs. The flower heads are cream to ochre-coloured, 3.5–5 mm (0.14–0.20 in) long, each head usually with five florets surrounded by fourteen to eighteen overlapping involucral bracts. The corymbs are hemispherical 10–100 mm (0.39–3.94 in) in diameter with between eighty and one hundred heads. Flowering occurs from January to April and the achenes are ribbed, reddish-brown, 0.8–1.0 mm (0.031–0.039 in) long with a pappus 2–3 mm (0.079–0.118 in) long.
