Description

Olearia minor is a small shrub to 1.5 m (4 ft 11 in) high, branchlets and leaf underside thickly covered with whitish, cottony hairs. The leaves are elliptic or egg-shaped, 1.5–8 mm (0.059–0.315 in) long, 1–2.5 mm (0.039–0.098 in) wide, arranged alternately, rounded or broadly pointed, green upper surface, occasional cobweb appearance when young, smooth or rough with short hairs. The single flowers are densely clustered, 12–22 mm (0.47–0.87 in) in diameter and borne at the end of branches, attached either with or without a stalk. The 7-12 white to pale mauve ligules (petals) 5.5–11 mm (0.22–0.43 in) long and the flower disc yellow or mauve. The 4-5 bracts are conical shaped, 4–6 mm (0.16–0.24 in) long, arranged in rows, smooth near the base, densely or sparingly covered with short, soft hairs near the either rounded or pointed apex. The dry, one-seeded fruit are narrowly oval shaped, about 1–2 mm (0.039–0.079 in) long, slightly ribbed, smooth or with dense, silky, flattened hairs. Flowering occurs from June to December.
